[PATCH 00/12] mtd: nand: davinci: stop using pdev->id as chipselect

We have the 'ti,davinci-chipselect' property in the device tree, but
when using platform data the driver silently uses the id field of
struct platform_device as the chipselect. This is confusing and we
almost broke the nand support again recently after converting the
platform to common clock framework (which changed the device id in the
clock lookup - the problem is gone now that we no longer acquire the
clock in the nand driver.

This series adds a new field to davinci-nand platform data, then makes
all board use it and finally modifies the two drivers that make use of
it.

Bartosz Golaszewski (12):
mtd: nand: davinci: store the core chipselect number in platform data
ARM: davinci: da830-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: da850-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: dm355-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: dm355-leopard: specify the chipselect in
davinci_nand_pdata
ARM: davinci: dm365-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: dm644x-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: mityomapl138: specify the chipselect in
davinci_nand_pdata
ARM: davinci: dm646x-evm: specify the chipselect in davinci_nand_pdata
ARM: davinci: neuros-osd2: specify the chipselect in
davinci_nand_pdata
mtd: nand: davinci: stop using pdev->id as chipselect
ARM: davinci: aemif: stop using pdev->id as nand chipselect
