hsi: controllers:remove redundant code

2015-10-30T15:10:40Z

Use devm_ioremap_resource() in order to make the code simpler, and remove redundant return value check of platform_get_resource() because this value is alreadytaken care by devm_ioremap_resource() Signed-off-by: Sanjeev Sharma Signed-off-by: Sebastian Reichel

hsi: omap_ssi_port: Prevent warning if cawake_gpio is not defined.

2015-10-14T11:24:44Z

The error handling path is broken as cawake_gpio was defined as unsigned integer causing the following warnings on boards that don't use SSI port and so don't have cawake_gpio defined. e.g. beagleboard C4.

drivers/hsi: include for modular omap_ssi code

2015-06-16T18:12:25Z

These files are built off of a tristate Kconfig option and also contain modular function calls so they should explicitly include module.h to avoid compile breakage during header shuffles done in the future. We change the one header file wich gives us coverage on both files: drivers/hsi/controllers/omap_ssi.c drivers/hsi/controllers/omap_ssi_port.c Cc: Sebastian Reichel Signed-off-by: Paul Gortmaker

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes.

hsi / OMAP / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-04T00:07:01Z

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Do that for the omap_ssi driver. Signed-off-by: Rafael J. Wysocki Acked-By: Sebastian Reichel

hsi: controllers: drop owner assignment from platform_drivers

2014-10-20T14:20:35Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

HSI: omap_ssi_port: Don't print uninitialized err

2014-10-19T22:11:59Z

Do not print err variable, that has nothing to do with the error. This fixes a warning, that is printed at build time: drivers/hsi/controllers/omap_ssi_port.c: In function ‘ssi_port_probe’: drivers/hsi/controllers/omap_ssi_port.c:1121:10: warning: ‘err’ may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Sebastian Reichel

HSI: omap_ssi: Fix return value check in ssi_debug_add_ctrl()

2014-07-30T22:20:33Z

In case of error, the function debugfs_create_*() returns NULL pointer not ERR_PTR() if debugfs is enabled. The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun Signed-off-by: Sebastian Reichel
