clk: imx: clk-imx8qxp: fix LVDS bypass, pixel and phy clocks

2024-02-05T20:14:29+00:00

[ Upstream commit 3f5f63adeea7e7aa715e101ffe4b4ac9705f9664 ]

To be compatible with SCU firmware based on 1.15 a different clock
routing for LVDS is needed.

clk: mmp: pxa168: Fix memory leak in pxa168_clk_init()

2024-02-05T20:14:29+00:00

[ Upstream commit 2fbabea626b6467eb4e6c4cb7a16523da12e43b4 ]

In cases where mapping of mpmu/apmu/apbc registers fails, the code path
does not handle the failure gracefully, potentially leading to a memory
leak. This fix ensures proper cleanup by freeing the allocated memory
for 'pxa_unit' before returning.

[ Upstream commit bfbea9e5667cfa9552c3d88f023386f017f6c308 ]

In cases where kcalloc() fails for the 'clk_data->clks' allocation, the
code path does not handle the failure gracefully, potentially leading
to a memory leak. This fix ensures proper cleanup by freeing the
allocated memory for 'clk_data' before returning.

The settings in the driver seem to have been taken from an older
release. Update them to match the latest values.

clk: qcom: gcc-sm8550: use collapse-voting for PCIe GDSCs

2024-01-25T23:35:38+00:00

[ Upstream commit 7e77a39265293ea4f05e20fff180755503c49918 ]

The PCIe GDSCs can be shared with other masters and should use the APCS
collapse-vote register when updating the power state.

This is specifically also needed to be able to disable power domains
that have been enabled by boot firmware using the vote register.

Following other recent Qualcomm platforms, describe this register and
the corresponding mask for the PCIe (and _phy) GDSCs.

clk: qcom: gcc-sm8550: Mark the PCIe GDSCs votable

[ Upstream commit e7fe73fc6b68ee97b1e8f124a66a5ee50d8d5e5b ]

The PCIe GDSCs on most Qualcomm platforms expect the OS to always
consider collapse requests as successful. This also concerns SM8550.

Add the VOTABLE flag to the GDSCs in question to comply with these
expectations.

All of the 8550's GCC GDSCs can and should use the retain registers so
as not to lose their state when entering lower power modes.

clk: rs9: Fix DIF OEn bit placement on 9FGV0241

[ Upstream commit 29d861b5d29b6c80a887e93ad982cbbf4af2a06b ]

On 9FGV0241, the DIF OE0 is BIT(1) and DIF OE1 is BIT(2), on the other
chips like 9FGV0441 and 9FGV0841 DIF OE0 is BIT(0) and so on. Increment
the index in BIT() macro instead of the result of BIT() macro to shift
the bit correctly on 9FGV0241.
