2020-09-22clk: keystone: sci-clk: add 10% slack to set_rateTero Kristo1-1/+2
Currently, we request exact clock rates from the firmware to be set with set_rate. Due to some rounding errors and internal functionality of the firmware itself, this can fail. Thus, add some slack to the set_rate functionality so that we are always guaranteed to pass. The firmware always attempts to use frequency as close to the target freq as possible despite the slack given here.

2020-09-22clk: qcom: dispcc: Update DP clk ops for phy designStephen Boyd2-9/+13
The clk_rcg2_dp_determine_rate() function is used for the DP pixel clk. This function should return the rate that can be achieved by the pixel clk in 'struct clk_rate_request::rate' and match the logic similar to what is seen in clk_rcg2_dp_set_rate(). But that isn't the case. Instead the code merely bubbles the rate request up to the parent of the pixel clk and doesn't try to do a rational approximation of the rate that would be achieved by picking some m/n value for the RCG. Let's change this logic so that we can assume the parent clk frequency is fixed (it is because it's the VCO of the DP PLL that is configured based on the link rate) and so that we can calculate what the m/n value will be and adjust the req->rate appropriately.

As i.MX21 support has been removed, get rid of its clock driver too. Signed-off-by: Fabio Estevam <festevam@gmail.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

mx35_clocks_init() has been used to register clocks on i.MX35 non-devicetree platforms. Now that i.MX is a devicetree-only platform, it is safe to remove mx35_clocks_init() as there are no more users.

Include the Tegra driver's clk.h to pull in the prototype definition for this function so that compilers don't warn about it being missing.

2020-09-21clk: tegra: Always program PLL_E when enabledThierry Reding1-3/+0
Commit bff1cef5f23a ("clk: tegra: Don't enable already enabled PLLs") added checks to avoid enabling PLLs that have already been enabled by the bootloader. However, the PLL_E configuration inherited from the bootloader isn't necessarily the one that is needed for the kernel. This can cause SATA to fail like this: [ 5.310270] phy phy-sata.6: phy poweron failed --> -110 [ 5.315604] tegra-ahci 70027000.sata: failed to power on AHCI controller: -110 [ 5.323022] tegra-ahci: probe of 70027000.sata failed with error -110 Fix this by always programming the PLL_E. This ensures that any mis- configuration by the bootloader will be overwritten by the kernel.
