2017-04-08	nvmem: sunxi-sid: add support for H3's SID controller	Icenowy Zheng	1	-0/+62
	The H3 SoC have a bigger SID controller, which has its direct read address at 0x200 position in the SID block, not 0x0. Also, H3 SID controller has some silicon bug that makes the direct read value wrong at cold boot, add code to workaround the bug. (This bug has already been fixed on A64 and later SoCs) Signed-off-by: Icenowy Zheng <icenowy@aosc.xyz> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-08	nvmem: sunxi-sid: read NVMEM size from device compatible	Icenowy Zheng	1	-4/+23
	Sometimes the SID device have more memory address space than the real NVMEM size (for the registers used to read/write the SID). Fetch the NVMEM size from device compatible, rather than the memory address space's length, in order to prepare for adding some registers-based read support.

2016-05-01	nvmem: sunxi-sid: remove nvmem regmap dependency	Srinivas Kandagatla	1	-45/+9
	This patch moves to nvmem support in the driver to use callback instead of regmap. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-10-04	nvmem: sunxi: Check for memory allocation failure	Maxime Ripard	1	-1/+10
	The sunxi_sid driver doesn't check for kmalloc return status before derefencing the returned pointer, which could lead to a NULL pointer dereference if kmalloc failed. Check for its return code to make sure it deosn't happen.

2015-08-05	nvmem: sunxi: Move the SID driver to the nvmem framework	Maxime Ripard	1	-0/+171
	Now that we have the nvmem framework, we can consolidate the common driver code. Move the driver to the framework, and hopefully, it will fix the sysfs file creation race.
