From 3a08e933415c58689797c5bdc825e78a808fffe1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 17 Jan 2017 12:03:38 +0100 Subject: [PATCH] mtd: spi-nor: add dt support for Everspin MRAMs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The MR25 family doesn't support JEDEC, so they need explicit mentioning in the list of supported spi IDs. This makes it possible to add these using for example: compatible = "everspin,mr25h40"; There was already an entry for mr25h256. Move that one out of the "keep for compatibility" section and put in a new group for Everspin MRAMs. Signed-off-by: Uwe Kleine-König Acked-by: Rob Herring Signed-off-by: Cyrille Pitchen --- Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt | 2 ++ drivers/mtd/devices/m25p80.c | 6 +++++- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt b/Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt index 2c91c03e7eb0..3e920ec5c4d3 100644 --- a/Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt +++ b/Documentation/devicetree/bindings/mtd/jedec,spi-nor.txt @@ -14,6 +14,8 @@ Required properties: at25df641 at26df081a mr25h256 + mr25h10 + mr25h40 mx25l4005a mx25l1606e mx25l6405d diff --git a/drivers/mtd/devices/m25p80.c b/drivers/mtd/devices/m25p80.c index 16a7df2a0246..c4df3b1bded0 100644 --- a/drivers/mtd/devices/m25p80.c +++ b/drivers/mtd/devices/m25p80.c @@ -289,7 +289,6 @@ static const struct spi_device_id m25p_ids[] = { * should be kept for backward compatibility. */ {"at25df321a"}, {"at25df641"}, {"at26df081a"}, - {"mr25h256"}, {"mx25l4005a"}, {"mx25l1606e"}, {"mx25l6405d"}, {"mx25l12805d"}, {"mx25l25635e"},{"mx66l51235l"}, {"n25q064"}, {"n25q128a11"}, {"n25q128a13"}, {"n25q512a"}, @@ -306,6 +305,11 @@ static const struct spi_device_id m25p_ids[] = { {"m25p40-nonjedec"}, {"m25p80-nonjedec"}, {"m25p16-nonjedec"}, {"m25p32-nonjedec"}, {"m25p64-nonjedec"}, {"m25p128-nonjedec"}, + /* Everspin MRAMs (non-JEDEC) */ + { "mr25h256" }, /* 256 Kib, 40 MHz */ + { "mr25h10" }, /* 1 Mib, 40 MHz */ + { "mr25h40" }, /* 4 Mib, 40 MHz */ + { }, }; MODULE_DEVICE_TABLE(spi, m25p_ids); -- 2.30.2
