+Subject: [PATCH 01/47] USB: OHCI: Add a generic platform device driver
+
+This adds a generic driver for platform devices. It works like the PCI
+driver and is based on it. This is for devices which do not have an own
+bus but their OHCI controller works like a PCI controller. It will be
+used for the Broadcom bcma and ssb USB OHCI controller.

+Subject: [PATCH 04/47] MIPS: ath79: fix AR933X WMAC reset code
+
+The current code puts the built-in WMAC device of the
+AR933X SoCs into reset instead of starting it. This
+causes a hard lock on AR933X based boards when the
+wireless driver tries to access the device.

+Subject: [PATCH 05/47] MIPS: ath79: separate common PCI code
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
+are common functions and only instance one of them
+can be present in a single kernel.
+
+Currently these functions can be built only if the
+CONFIG_SOC_AR724X option is selected. However the
+ath79 platform contain support for the AR71XX SoCs,.
+The AR71XX SoCs have a differnet PCI controller,
+and those will require a different code.
+
+Move the common PCI code into a separeate file in
+order to be able to use that with other SoCs as
+well.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
-are common functions and only instance one of them
-can be present in a single kernel.
-
-Currently these functions can be built only if the
-CONFIG_SOC_AR724X option is selected. However the
-ath79 platform contain support for the AR71XX SoCs,.
-The AR71XX SoCs have a differnet PCI controller,
-and those will require a different code.
-
-Move the common PCI code into a separeate file in
-order to be able to use that with other SoCs as
-well.

-Subject: [PATCH 05/35] MIPS: ath79: add a common PCI registration function
-
-The current code unconditionally registers the AR724X
-specific PCI controller, even if the kernel is running
-on a different SoC.
-
-Add a common function for PCI controller registration,
-and only register the AR724X PCI controller if the kernel
-is running on an AR724X SoC.
-
-Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
-
-v4: - simplify ath79_register_pci function
-v3: - fix compile error if CONFIG_PCI is not defined
- - add __init annotation to ath79_register_pci
-v2: - no changes

+Subject: [PATCH 13/47] MIPS: ath79: fix broken ar724x_pci_{read,write} functions
+
+The current ar724x_pci_{read,write} functions are
+broken. Due to that, pci_read_config_byte returns
+with bogus values, and pci_write_config_{byte,word}
+unconditionally clears the accessed PCI configuration
+registers instead of changing the value of them.
+
+The patch fixes the broken functions, thus the PCI
+configuration space can be accessed correctly.

+Subject: [PATCH 14/47] MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCs
+
+The PCI controller of the AR724X SoCs has a hardware
+bag. If the BAR0 register of the PCI device is set to
+the proper base address, the memory address space of
+the device is not accessible.
+
+When the device driver tries to access the memory
+address space of the PCI device, it leads to data
+bus error, similiar to this:

+Subject: [PATCH 15/47] MIPS: ath79: fix a wrong IRQ number
+
+The Ubiquiti XM board setup code uses an invalid
+IRQ number, because it if above of NR_IRQS. This
+leads to failed 'request_irq' calls:
+
+ ath9k 0000:00:00.0: request_irq failed
+ ath9k: probe of 0000:00:00.0 failed with error -22
+
+Preserve some IRQ numbers for the built-in IRQ
+controller of PCI host controllers in the
+AR71XX/AR724X SoCs, and use the correct IRQ
+number in the board setup code.

-Subject: [PATCH 10/35] MIPS: ath79: fix broken ar724x_pci_{read,write} functions
-
-The current ar724x_pci_{read,write} functions are
-broken. Due to that, pci_read_config_byte returns
-with bogus values, and pci_write_config_{byte,word}
-unconditionally clears the accessed PCI configuration
-registers instead of changing the value of them.
-
-The patch fixes the broken functions, thus the PCI
-configuration space can be accessed correctly.

+Subject: [PATCH 16/47] MIPS: ath79: add PCI IRQ handling code for AR724X SoCs
+
+The PCI Host Controller of the AR724x SoC has a
+built-in IRQ controller. The current code does
+not supports that, so the IRQ lines wired to this
+controller are not usable. This leads to failed
+'request_irq' calls:
+
+ ath9k 0000:00:00.0: request_irq failed
+ ath9k: probe of 0000:00:00.0 failed with error -89
+
+This patch adds support for the IRQ controller
+in order to make PCI IRQs work.

-Subject: [PATCH 11/35] MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCs
-
-The PCI controller of the AR724X SoCs has a hardware
-bag. If the BAR0 register of the PCI device is set to
-the proper base address, the memory address space of
-the device is not accessible.
-
-When the device driver tries to access the memory
-address space of the PCI device, it leads to data
-bus error, similiar to this:
-
-Data bus error, epc == 801f69a0, ra == 801f698c

+
+This can be avoided by calling the 'ar724x_pci_add_data'
+function from the board specific setup code. However it
+makes no sense to use that function for every board,
+especially when the board does not needs to set the
+platform_data field of any PCI device.
+
+The patch allows the board setup code to specify a board
+specific function if that is required.

+Subject: [PATCH 20/47] MIPS: ath79: allow to use SoC specific PCI IRQ maps
+
+The PCI controllers in the AR71XX and in the
+AR724X SoCs are different, and both of them
+uses different IRQ wiring.
+
+The patch modifies the 'pcibios_map_irq' function
+in order to allow to use different IRQ maps for
+the different SoCs. The patch also adds a function,
+which lets the board setup code to override the
+default IRQ map.

-
-This can be avoided by calling the 'ar724x_pci_add_data'
-function from the board specific setup code. However it
-makes no sense to use that function for every board,
-especially when the board does not needs to set the
-platform_data field of any PCI device.
-
-The patch allows the board setup code to specify a board
-specific function if that is required.
-
-Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
-
-v2: - no changes
-
-The pci_irq_map function can throw another NULL pointer
-dereference, that will be fixed in a subsequent patch.

-Subject: [PATCH 16/35] MIPS: ath79: add support for the PCI host controller of the AR71XX SoCs
-
-The Atheros AR71XX SoCs have a built-in PCI Host Controller.
-This patch adds a driver for that, and modifies the relevant
-files in order to allow to register the PCI controller from
-board specific setup.

-Subject: [PATCH 17/35] MIPS: ath79: allow to use SoC specific PCI IRQ maps
-
-The PCI controllers in the AR71XX and in the
-AR724X SoCs are different, and both of them
-uses different IRQ wiring.
-
-The patch modifies the 'pcibios_map_irq' function
-in order to allow to use different IRQ maps for
-the different SoCs. The patch also adds a function,
-which lets the board setup code to override the

+Subject: [PATCH 29/47] MIPS: ath79: rework IP2/IP3 interrupt handling
+
+The current implementation assumes that flushing the
+DDR writeback buffer is required for IP2/IP3 interrupts,
+however this is not true for all SoCs.
+
+Use SoC specific IP2/IP3 handlers instead of flushing
+the buffers in the dispatcher code.

-Subject: [PATCH 26/35] MIPS: ath79: rework IP2/IP3 interrupt handling
-
-The current implementation assumes that flushing the
-DDR writeback buffer is required for IP2/IP3 interrupts,
-however this is not true for all SoCs.
-
-Use SoC specific IP2/IP3 handlers instead of flushing
-the buffers in the dispatcher code.

+Subject: [PATCH 34/47] MIPS: ath79: add PCI_AR724X Kconfig symbol
+
+The AR724X specific PCI code can be used for the
+AR934X SoCs, however it can be selected only if
+SOC_AR724X is set.
+
+Introduce a new Kconfig symbol in order to be able
+to use the code for AR934X as well.

-
-The AR724X specific PCI code can be used for the
-AR934X SoCs, however it can be selected only if
-SOC_AR724X is set.
-
-Introduce a new Kconfig symbol in order to be able
-to use the code for AR934X as well.

+Subject: [PATCH 37/47] MIPS: ath79: use correct IRQ number for the OHCI controller on AR7240
+
+The currently assigned IRQ number to the OHCI
+controller is incorrect for the AR7240 SoC, and
+that leads to the following error message from
+the OHCI driver:
+
+ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
+ath79-ohci ath79-ohci: Atheros built-in OHCI controller
+ath79-ohci ath79-ohci: new USB bus registered, assigned bus number 1
+ath79-ohci ath79-ohci: irq 14, io mem 0x1b000000
+hub 1-0:1.0: USB hub found
+hub 1-0:1.0: 1 port detected
+usb 1-1: new full-speed USB device number 2 using ath79-ohci
+ath79-ohci ath79-ohci: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
+
+Fix this by using the correct IRQ number.

+
+The driver uses the "as fast as it can" approach
+to drive the SCK signal. However this does not
+work with certain low speed SPI chips (e.g. the
+PCF2123 RTC chip). Add per-bit slowdowns in order
+to be able to use the driver with such chips as
+well.

-
-The spi_bitbang driver calls the chipselect function
-of the driver from spi_bitbang_setup in order to
-deselect the given SPI chip, so we don't have to
-initialize the CS line here.

+
+Currently we are initializing the SPI controller in
+the chip select line function, and that function is
+called once for each SPI device on the bus. If a
+board has multiple SPI devices, the controller will
+be initialized multiple times.
+
+Introduce ath79_spi_{en,dis}able helper functions,
+and call those from probe/response in order to avoid
+the mutliple initialization of the controller.
