* mtd: nand: orion: improve handling of optional clockSimon Baatz2017-03-291-7/+13
| | | | | | | | | | | | The clock gate used by orion_nand is not available on all platforms. When getting this optional clock gate, the code masked all errors. Let's be more precise here and actually only allow ENOENT. EPROBE_DEFER is handled like any other error code since probe deferral is not supported by drivers using module_platform_driver_probe().

* mtd: nand: orion: fix clk handlingSimon Baatz2017-03-291-21/+21
| | | | | | | | | | | | | | | | | | | The clk handling in orion_nand.c had two problems: - In the probe function, clk_put() was called for an enabled clock, which violates the API (see documentation for clk_put() in include/linux/clk.h) - In the error path of the probe function, clk_put() could be called twice for the same clock. In order to clean this up, use the managed function devm_clk_get() and store the pointer to the clk in the driver data.

* mtd: nand: drop unnecessary partition parser dataBrian Norris2015-11-111-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | All of these drivers set up a parser data struct just to communicate DT partition data. This field has been deprecated and is instead supported by telling nand_scan_ident() about the 'flash_node'. This patch: * sets chip->flash_node for those drivers that didn't already (but used OF partitioning) * drops the parser data * switches to the simpler mtd_device_register() where possible, now that we've eliminated one of the auxiliary parameters Now that we've assigned chip->flash_node for these drivers, we can probably rely on nand_dt_init() to do more of the DT parsing for us, but for now, I don't want to fiddle with each of these drivers. The parsing is done in duplicate for now on some drivers. I don't think this should break things. (Famous last words.)

| * mtd: orion_nand: fix error code path in probeMichael Opdenacker2014-10-221-28/+11

This simplifies simplifies the error management code, and brings the below improvements or changes: A. Fixing a bug reported by "make coccicheck": If "board = devm_kzalloc()" fails, the probe() function jumps incorrectly to label "no_res" and therefore returns without running iounmap(). B. Requesting the memory region Using devm_ioremap_resource() makes the probe() function request the corresponding memory region before running ioremap(), as it is supposed to do. C. Standardizing the error codes: The use of devm_ioremap_resource() changes the return value: * -ENOMEM instead of -EIO in case of ioremap() failure, * -EINVAL instead of -ENODEV in case of platform_get_resource() failure.

| | | | | | | | | | | | | | | | | | | | orion_nand_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by Nicolas Pitre platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.

| | | | | | | | | | | | | | | GCC 4.3.3 and 4.4.1 happily moves the dword load instruction out of the loop in orion_nand_read_buf. This patch makes the instruction volatile to avoid the issue. I've discussed this at gcc-help, refer to the thread at http://gcc.gnu.org/ml/gcc-help/2009-08/msg00187.html The early clobber is added to avoid the destination registers and the source register overlapping.

| | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD NAND platform drivers, to re-enable auto loading. NOTE: at91_nand for some reason disallows modular builds. I'm assuming that's just an oversight that will be fixed.
