2020-07-21clk: qcom: gcc: Make disp gpll0 branch aon for sc7180/sdm845Taniya Das
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.

The HSDK pll driver uses the devm_ioremap_resource function, but does not specify a dependency on IOMEM in Kconfig. This causes a build failure on architectures without IOMEM, for example, UML (notably with make allyesconfig). Fix this by making CONFIG_CLK_HSDK depend on CONFIG_IOMEM.

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.

2020-06-24clk: meson: meson8b: Drop CLK_IS_CRITICAL from fclk_div2Martin Blumenstingl
Drop CLK_IS_CRITICAL from fclk_div2. This was added because we didn't know the relation between this clock and RGMII Ethernet. It turns out that fclk_div2 is used as "timing adjustment clock" to generate the RX delay on the MAC side - which was enabled by u-boot on Odriod-C1. When using the RX delay on the PHY side or not using a RX delay at all then this clock can be disabled.

2020-06-22clk: vc5: Enable addition output configurations of the VersaclockAdam Ford
The existing driver is expecting the Versaclock to be pre-programmed, and only sets the output frequency. Unfortunately, not all devices are pre-programmed, and the Versaclock chip has more options beyond just the frequency. This patch enables the following additional features: - Programmable voltage: 1.8V, 2.5V, or 3.3V​ - Slew Percentage of normal: 85%, 90%, or 100% - Output Type: LVPECL, CMOS, HCSL, or LVDS Signed-off-by: Adam Ford <aford173@gmail.com> Link: https://lore.kernel.org/r/20200603154329.31579-3-aford173@gmail.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2020-06-22dt: Add additional option bindings for IDT VersaClockAdam Ford
The VersaClock driver now supports some additional bindings to support child nodes which can configure optional settings like mode, voltage and slew. This patch updates the binding document to describe what is available in the driver.

2020-06-22clk: vc5: Allow Versaclock driver to support multiple instancesAdam Ford
Currently, the Versaclock driver is only expecting one instance and uses hard-coded names for the various clock names. Unfortunately, this is a problem when there is more than one instance of the driver, because the subsequent instantiations of the driver use the identical name. Each clock after the fist fails to load, because the clock subsystem cannot handle two clocks with identical name. This patch removes the hard-coded name arrays and uses kasprintf to assign clock names based on names of their respective node and parent node which gives each clock a unique identifying name. For a verasaclock node with a name like: versaclock5: versaclock_som@6a The updated clock names would appear like: versaclock_som.mux versaclock_som.out0_sel_i2cb versaclock_som.pfd versaclock_som.pll versaclock_som.fod3 versaclock_som.out4 versaclock_som.fod2 versaclock_som.out3 versaclock_som.fod1 versaclock_som.out2 versaclock_som.fod0 versaclock_som.out1 Signed-off-by: Adam Ford <aford173@gmail.com> Link: https://lore.kernel.org/r/20200603154329.31579-1-aford173@gmail.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>
