When conditionally checking for heap existence of a certian address in pvr_vm_bind_op_map_init the condition whether the map request comes from a user is incorrect: The context must not be the kernel-context to be a user(space) context and should be looked up in pvr_heaps. That makes addresses coming from userspace not being verfied against the defined ranges and prevents firmware loading for meta cores.

Even though we were rolling our own custom state for the vc4 HDMI controller driver, we were still using the generic helper to destroy that state. It was mostly working since the underlying state is the first member of our state so the pointers are probably equal in all relevant cases, but it's still fragile so let's fix this properly.

The write mask bit is used to make sure when writing config done bit for one VP will not overwrite the other. Unfortunately, the write mask bit is missing on rk3566/8, that means when we write to these bits, it will not take any effect. We need this to make the vop work properly after rk3566/8 variants.

The enable bit and transform offset of cluster windows should be cleared when it work at linear mode, or we may have a iommu fault issue on rk3588 which cluster windows switch between afbc and linear mode. As the cluster windows of rk3568 only supports afbc format so is therefore not affected. Signed-off-by:

At first we thought the half_block_en bit in AFBCD_CTRL register only work in afbc mode. But the fact is that it control the line buffer in all mode(afbc/tile/linear), so we need configure it in all case. As the cluster windows of rk3568 only supports afbc format so is therefore not affected. Signed-off-by:

This reverts commit b63a553e. regcache_sync will try to reload the configuration in regcache to hardware, but the registers of 4 Cluster windows and Esmart1/2/3 on the upcoming rk3588 can not be set successfully before internal PD power on. Also it's better to keep the hardware register as it is before we really enable it. So let's revert this version, and keep the first version: commit afa965a4 ("drm/rockchip: vop2: fix suspend/resume") Signed-off-by:

It's the ti_sn65dsi86.pwm auxiliary driver that creates the pwmchip, so let the auxiliary device be the parent of the pwm device. Note that getting a reference to the ti-sn65dsi86's pwm using pwm_get() isn't affected by this change as ti_sn65dsi86_add_aux_device() sets the auxiliary device's of_node to that of the main device. Also change PM runtime tracking and diagnostic messages to use that one. After enabling runtime PM operation for the auxiliary device, all works as expected as parent devices are handled just fine.

The AVCL register, according to the datasheet, comes in increments of -0.2v between -4.4v (represented by 0x0) to -5.0v (represented by 0x3). The current calculation is done by adding the defined AVCL value in mV to -4400 and then dividing by 200 to get the register value. Unfortunately if I subtract -4400 from -4400 I get -8800, which divided by 200 gives me -44. If I instead subtract -4400 from -4400 I get 0, which divided by 200 gives me 0. Based on the datasheet this is the expected register value. Fixes: 83b7a8e7 ("drm/panel/panel-sitronix-st7701: Parametrize voltage and timing") Signed-off-by:
