bus: sunxi-rsb: Return correct data when mixing 16-bit and 8-bit reads

2020-04-17T08:49:56Z

[ Upstream commit a43ab30dcd4a1abcdd0d2461bf1cf7c0817f6cd3 ] When doing a 16-bit read that returns data in the MSB byte, the RSB_DATA register will keep the MSB byte unchanged when doing the following 8-bit read. sunxi_rsb_read() will then return a result that contains high byte from 16-bit read mixed with the 8-bit result. The consequence is that after this happens the PMIC's regmap will look like this: (0x33 is the high byte from the 16-bit read) % cat /sys/kernel/debug/regmap/sunxi-rsb-3a3/registers 00: 33 01: 33 02: 33 03: 33 04: 33 05: 33 06: 33 07: 33 08: 33 09: 33 0a: 33 0b: 33 0c: 33 0d: 33 0e: 33 [snip] Fix this by masking the result of the read with the correct mask based on the size of the read. There are no 16-bit users in the mainline kernel, so this doesn't need to get into the stable tree.

bus: ti-sysc: Fix 1-wire reset quirk

2020-03-12T12:00:31Z

commit aec551c7a00fb7eae049c0c4cc3208ca53e26355 upstream. Because of the i2c quirk we have the reset quirks named in a confusing way. Let's fix the 1-wire quirk accordinlyg. Then let's switch to using better naming later on. Fixes: 4e23be473e30 ("bus: ti-sysc: Add support for module specific reset quirks") Signed-off-by: Tony Lindgren Signed-off-by: Greg Kroah-Hartman

bus: tegra-aconnect: Remove PM_CLK dependency

commit 2f56acf818a08a9187ac8ec6e3d994fc13dc368d upstream. The ACONNECT bus driver does not use pm-clk interface anymore and hence the dependency can be removed from its Kconfig option.

bus: moxtet: fix potential stack buffer overflow

2020-02-19T18:53:04Z

commit 3bf3c9744694803bd2d6f0ee70a6369b980530fd upstream. The input_read function declares the size of the hex array relative to sizeof(buf), but buf is a pointer argument of the function. The hex array is meant to contain hexadecimal representation of the bin array.

bus: ti-sysc: Fix missing force mstandby quirk handling

2020-02-01T09:34:51Z

[ Upstream commit 93c60483b5feefced92b869d5f97769495bc6313 ] Commit 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for musb") added quirk handling for mstandby quirk but did not consider that we also need a quirk variant for SYSC_QUIRK_FORCE_MSTANDBY. We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to additionally also configure no-idle mode when enabled.

bus: ti-sysc: Fix iterating over clocks

2020-01-23T07:22:28Z

commit 2c81f0f6d3f52ac222a5dc07a6e5c06e1543e88b upstream. Commit d878970f6ce1 ("bus: ti-sysc: Add separate functions for handling clocks") separated handling of optional clocks from the main clocks, but introduced an issue where we do not necessarily allocate a slot for both fck and ick clocks, but still assume fixed slots for enumerating over the clocks. Let's fix the issue by ensuring we always have slots for both fck and ick even if we don't use ick, and don't attempt to enumerate optional clocks if not allocated. In the long run we might want to simplify things a bit by only allocating space only for the optional clocks as we have only few devices with optional clocks.
