Lucid PCAL_DONE is different from trion. Signed-off-by:
-
Jonathan Marek authored
Fixed ops were already identical, this adds support for non-fixed ops by sharing between trion and lucid. This also changes the names for trion ops to be consistent with the rest. Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this. Signed-off-by:

The display gpll0 branch clock inside GCC needs to always be enabled. Otherwise the AHB clk (disp_cc_mdss_ahb_clk_src) for the display clk controller (dispcc) will stop clocking while sourcing from gpll0 when this branch inside GCC is turned off during unused clk disabling. We can never turn this branch off because the AHB clk for the display subsystem is needed to read/write any registers inside the display subsystem including clk related ones. This makes this branch a really easy way to turn off AHB access to the display subsystem and cause all sorts of mayhem. Let's just make the clk ops keep the clk enabled forever and ignore any attempts to disable this clk so that dispcc accesses keep working. Signed-off-by:

Each of the CPU clusters (Power and Perf) on msm8996 are clocked via 2 PLLs, a primary and alternate. There are also 2 Mux'es, a primary and secondary all connected together as shown below +-------+ XO | | +------------------>0 | | | PLL/2 | SMUX +----+ +------->1 | | | | | | | +-------+ | +-------+ | +---->0 | | | | +---------------+ | +----------->1 | CPU clk |Primary PLL +----+ PLL_EARLY | | +------> | +------+-----------+ +------>2 PMUX | +---------------+ | | | | | +------+ | +-->3 | +--^+ ACD +-----+ | +-------+ +---------------+ +------+ | |Alt PLL | | | +---------------------------+ +---------------+ PLL_EARLY The primary PLL is what drives the CPU clk, except for times when we are reprogramming the PLL itself (for rate changes) when we temporarily switch to an alternate PLL. A subsequent patch adds support to switch between primary and alternate PLL during rate changes. The primary PLL operates on a single VCO range, between 600MHz and 3GHz. However the CPUs do support OPPs with frequencies between 300MHz and 600MHz. In order to support running the CPUs at those frequencies we end up having to lock the PLL at twice the rate and drive the CPU clk via the PLL/2 output and SMUX. So for frequencies above 600MHz we follow the following path Primary PLL --> PLL_EARLY --> PMUX(1) --> CPU clk and for frequencies between 300MHz and 600MHz we follow Primary PLL --> PLL/2 --> SMUX(1) --> PMUX(0) --> CPU clk ACD stands for Adaptive Clock Distribution and is used to detect voltage droops.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot. Signed-off-by:
