Hi Archit,
I have enabled splash screen (penguin) in bootloader with fastboot oem
select-display-panel hdmi. Kernel crashes during boot. I identified that
there is issue with below two smmu clocks.
static struct clk_branch smmu_mdp_ahb_clk = {
.halt_reg = 0x2454,
.clkr = {
.enable_reg = 0x2454,
.enable_mask = BIT(0),
static struct clk_branch smmu_mdp_axi_clk = {
.halt_reg = 0x2458,
.clkr = {
.enable_reg = 0x2458,
.enable_mask = BIT(0),
I tried to reset the clocks in mmcc_msm8996_probe, with the below changes.
* regmap_update_bits(regmap, 0x2454, BIT(0), 0);*
* regmap_update_bits(regmap, 0x2458, BIT(0), 0);*
Then i don't see a kernel crash but blue screen appears after penguin for
some time. Then HDMI display comes up.
Can you please let me know better way to reset smmu clocks?
Thanks,
Pradeep
