2014-10-20mtd: devices: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-08-31mtd: bcm47xxsflash: convert kzalloc to avoid invalid accessLibo Chen1-12/+4
mtd is just member of bcm47xxsflash, so we should free bcm47xxsflash not its member. So I use devm_kazlloc instead of kazlloc to avoid it. * Changelog: convert to devm_kzalloc Signed-off-by: Libo chen <libo.chen@huawei.com> Suggested-by: Andy Shevchenko <andy.shevchenko@gmail.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> [Brian: fixed conflicts] Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2013-08-05mtd: bcm47xxsflash: implement ChipCommon R/W opsRafał Miłecki1-0/+13
They are needed for erasing/writing. Use a magic pointers and small functions to prepare code for adding other buses support in the future (like SSB).

2013-04-05mtd: bcm47xxsflash: store info about flash typeRafał Miłecki1-0/+9
It's going to be needed for erase and write operations, they differ between Atmel and ST flashes. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2013-04-05mtd: bcm47xxsflash: keep a reference to the BCMARafał Miłecki1-0/+2
To implement erase and write support we need to "talk" with ChipCommon BCMA core which serial flash it attached to. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2013-04-05mtd: devices: add const qualifiersArtem Bityutskiy1-1/+1
Be a bit stricter and add few more 'const' qualifiers. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2013-02-04mtd: bcm47xxsflash: register this as normal driverHauke Mehrtens1-1/+2
When platform_driver_probe() is used and no device is registered for this driver -ENODEV is returned and and error message is shown. Not all BCM47xx SoC have a serial flash chip controller and chip and for them an error message was shown.

2013-02-04mtd: bcm47xxsflash: write number of written bytesHauke Mehrtens1-0/+1
The callback assumes the number of read bytes is written to retlen. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

2012-09-29mtd: basic (read only) driver for BCMA serial flashRafał Miłecki1-0/+105
This registers MTD driver for serial flash platform device. Right now it supports reading only, writing still has to be implemented. Artem: minor amendments.
