reset: hi6220: Set module license so that it can be loaded

2017-05-24T08:53:41Z

The hi6220_reset driver can be built as a standalone module yet it cannot be loaded because it depends on GPL exported symbols. Lets set the module license so that the module loads, and things like the on-board kirin drm starts working. Signed-off-by: Jeremy Linton Reviewed-by: Xinliang Liu Signed-off-by: Philipp Zabel

reset: add exported __reset_control_get, return NULL if optional

2017-04-04T15:36:10Z

Rename the internal __reset_control_get/put functions to __reset_control_get/put_internal and add an exported __reset_control_get equivalent to __of_reset_control_get that takes a struct device parameter. This avoids the confusing call to __of_reset_control_get in the non-DT case and fixes the devm_reset_control_get_optional function to return NULL if RESET_CONTROLLER is enabled but dev->of_node == NULL.

reset: sunxi: fix for 64-bit compilation

2017-03-15T11:19:12Z

The Allwinner reset controller has 32-bit registers, so translating the reset cell number into a register and bit offset should not use any architecture dependent data size. Otherwise this breaks for 64-bit architectures like arm64. Fix this by making it clear that it's the hardware register width which matters here in the calculation.

reset-socfpga: Fix nr_resets property

2017-03-08T08:36:45Z

The SoC-FPGA reset controller driver defines NR_BANKS as 4 and uses that define for two unrelated purposes. It is used 1. as an increment for reset line banks which are 32-bit registers with 4-byte aligned addresses. 2. as the total number of reset line banks which together with the number of resets per bank (32) limits the total number of useable resets to 128 and the highest useable reset ID to 127. This is clearly wrong as there are resets with higher IDs than 127 defined in include/dt-bindings/reset/altr,rst-mgr.h and altr,rst-mgr-a10.h. The patch introduces a new define BANK_INCREMENT for calculating the register addresses as before and increases NR_BANKS to 8 for useable reset IDs up to 255.

reset: pistachio: make it explicitly non-modular

2017-03-08T08:36:45Z

The Kconfig currently controlling compilation of this code is: drivers/reset/Kconfig:config RESET_PISTACHIO drivers/reset/Kconfig: bool "Pistachio Reset Driver" if COMPILE_TEST ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
