Dirk Behme [Thu, 9 May 2013 05:19:52 +0000 (07:19 +0200)]
spi: mxc_spi: Fix pre and post divider calculation

Fix two issues with the calculation of pre_div and post_div:

1. pre_div: While the calculation of pre_div looks correct, to set the
CONREG[15-12] bits pre_div needs to be decremented by 1:

The i.MX 6Dual/6Quad Applications Processor Reference Manual (IMX6DQRM
Rev. 0, 11/2012) states:

CONREG[15-12]: PRE_DIVIDER
0000 Divide by 1
0001 Divide by 2
0010 Divide by 3
...
1101 Divide by 14
1110 Divide by 15
1111 Divide by 16

I.e. if we want to divide by 2, we have to write 1 to CONREG[15-12].

2. In case the post divider becomes necessary, pre_div will be divided by
16. So set pre_div to 16, too. And not 15.

Both issues above are tested using the following examples:

clk_src = 60000000 (60MHz, default i.MX6 ECSPI clock)

a) max_hz == 23000000 (23MHz, max i.MX6 ECSPI read clock)

-> pre_div =  3 (divide by 3 => CONREG[15-12] == 2)
-> post_div = 0 (divide by 1 => CONREG[11- 8] == 0)
               => 60MHz / 3 = 20MHz SPI clock

b) max_hz == 2000000 (2MHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 1  (divide by  2 => CONREG[11- 8] == 1)
               => 60MHz / 32 = 1.875MHz SPI clock

c) max_hz == 1000000 (1MHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 2  (divide by  4 => CONREG[11- 8] == 2)
               => 60MHz / 64 = 937.5kHz SPI clock

d) max_hz == 500000 (500kHz)

-> pre_div =  16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 3  (divide by  8 => CONREG[11- 8] == 3)

ARM: OMAP5: Fix warm reset with USB cable connected

Warm reset on OMAP5 freezes when USB cable is connected.
Fix requires PRM_RSTTIME.RSTTIME1 to be programmed
with the time for which reset should be held low for the
voltages and the oscillator to reach stable state.

There are 3 parameters to be considered for calculating
the time, which are mostly board and PMIC dependent.
-1- Time taken by the Oscillator to shut + restart
-2- PMIC OTP times
-3- Voltage rail ramp times, which inturn depends on the
PMIC slew rate and value of the voltage ramp needed.

In order to keep the code in u-boot simple, have a way
for boards to specify a pre computed time directly using
the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC'
option. If boards fail to specify the time, use a default
as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead.
Using the default value translates into some ~22ms and should work in
all cases.
However in order to avoid this large delay hiding other bugs,
its recommended that all boards look at their respective data
sheets and specify a pre computed and optimal value using
'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC'

In order to help future board additions to compute this
config option value, add a README at doc/README.omap-reset-time
which explains how to compute the value. Also update the toplevel

mtd: nand: add driver for diskonchip g4 nand flash

This patch adds a driver for the diskonchip G4 nand flash device.  It is based
on the driver from the linux kernel.

This also includes a separate SPL driver.  A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly).  The SPL driver basically mimics how
a typical IPL reads data from the device.  The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints).  Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.
