Wolfram Sang	ea84768e9a	soc: qcom: drop owner assignment from platform_drivers 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>	2014-10-20 16:21:34 +02:00
Srinivas Kandagatla	fa9eb32418	drivers/soc: qcom: do not disable the iface clock in probe since commit `31964ffebb` ("tty: serial: msm: Remove direct access to GSBI")' serial hangs if earlyprintk are enabled. This hang is noticed only when the GSBI driver is probed and all the earlyprintks before gsbi probe are seen on the console. The reason why it hangs is because GSBI driver disables hclk in its probe function without realizing that the serial IP might be in use by a bootconsole. As gsbi driver disables the clock in probe the bootconsole locks up. Turning off hclk's could be dangerous if there are system components like earlyprintk using the hclk. This patch fixes the issue by delegating the clock management to probe and remove functions in gsbi rather than disabling the clock in probe.

Arnd Bergmann	1b7f0c7b93	soc: qcom: fix of_device_id table The match tables must be zero-terminated, and Kbuild now helpfully fails to link the kernel if that isn't the case. Signed-off-by: Arnd Bergmann <arnd@arndb.de>	2014-05-26 21:27:09 +02:00
Andy Gross	5d144e36b7	soc: qcom: Add GSBI driver The GSBI (General Serial Bus Interface) driver controls the overarching configuration of the shared serial bus infrastructure on APQ8064, IPQ8064, and earlier QCOM processors. The GSBI supports UART, I2C, SPI, and UIM functionality in various combinations.
