It turns out that this PLL is not used on Tegra210, so there's no need to enable it via the init table. Remove the init table entry for this PLL to avoid it getting enabled at boot time. If the bootloader enabled it and forgot to turn it off, the common clock framework will now know to disable it because it is unused.

As 'clk-raspberrypi' depends on RPi's firmware interface, which might be configured as a module, the cpu clock might not be available for the cpufreq driver during it's init process.

2019-06-25clk: Simplify clk_core_can_round()Geert Uytterhoeven
A boolean expression already evaluates to true or false, so there is no need to check the result and return true or false explicitly. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2019-06-25clk: socfpga: stratix10: fix divider entry for the emac clocksDinh Nguyen
The fixed dividers for the emac clocks should be 2 not 4. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2019-06-25clk: socfpga: stratix10: add additional clocks needed for the NAND IPDinh Nguyen
The nand_clk is actually called the nand_x_clk and the parent is the l4_mp_clk, not the l4_main_clk. The nand_clk is a child of the nand_x_clk and has a fixed divider of 4. The same is true for the nand_ecc_clk. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2019-06-25clk: Add clk_bulk_get_optional() functionSylwester Nawrocki
clk_bulk_get_optional() allows to get a group of clocks where one or more is optional. For a not available clock, e.g. not specifed in the clock consumer node in DT, its respective struct clk pointer will be NULL. This allows for operating on a group of returned clocks (struct clk_bulk_data array) with existing clk_bulk* APIs.

2019-06-25clk: Simplify debugfs printing and add a newlineStephen Boyd
The possible parent printing function duplicates a bunch of if conditions. Pull that into another function so we can print an extra character at the end, either a space or a newline. This way we can add the required newline that got lost here and also shorten the code.
