...s this patch is still required for enabling the GPU. Is there anything blocking it (firmware not available yet in liux-firmware?)

..., then I guess we can commit these last two patches for 3.19. A resend after the 3.18 merge window might help. > On Mon, May 19, 2014 at 06:24:10PM +0900, Alexandre Courbot wrote: >> Signed-off-by: Alexandre Courbot <acourbot at nvidia.com> >> --- >> arch/arm/boot/dts/tegra124-jetson-tk1.dts | 8 +++++++- >> 1 file changed, 7 insertions(+), 1 deletion(-) >> >> diff --git a/arch/arm/boot/dts/tegra124-jetson-tk1.dts b/arch/arm/boot/dts/tegra124-jetson-tk1.dts >> index e31fb61a81d3..15a194d1277f 100644 >> --- a/arch/arm/boot/dts/tegra124-jetso...

The Tegra124 and later Tegra SoCs have a sepatate rail gating register to enable/disable the clamp. The original function tegra_powergate_remove_clamping() is not sufficient for the enable function. So add a new function which is dedicated to the GPU rail gating. Also don't refer to the powergate ID since t...

...lled once, before calling their init counterparts. For gk20a, after the BAR1 teardown function is called, the device is hanging during the initialisation of the FB sub-device. At this point it is unclear why this is happening and this is still under investigation. However, this change is preventing Tegra124 devices from booting when Nouveau is enabled. To allow Tegra124 to boot, remove the teardown helper for gk20a. This is based upon a previous patch by Guillaume Tucker but limits the workaround to only gk20a GPUs.
