2020-08-03clk: bcm2835: Do not use prediv with bcm2711's PLLsNicolas Saenz Julienne1-4/+21
Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL feedback loop. Bypass it by zeroing fb_prediv_mask when running on bcm2711. Note that, since the prediv configuration bits were re-purposed, this was triggering miscalculations on all clocks hanging from the VPU clock, notably the aux UART, making its output unintelligible.

2020-07-31dt-bindings: clock: Fix YAML schemas for LPASS clocks on SC7180Douglas Anderson1-4/+10
The YAML schemas that landed forgot one clock: "bi_tcxo". Presumably the bindings were developed against the v4 version of the driver and when the ".name" was removed in v5 of the driver things broke. While touching this, add the needed includes in each example. I believe both examples are supposed to be independent of each other. Let's fix the bindings.

2020-07-24clk: Add support for enabling/disabling clocks from debugfsMike Tipton1-0/+29
For test and debug purposes, it's simple enough to enable or disable clocks from shell. Add a new debugfs file 'clk_prepare_enable' that calls clk_prepare_enable() when writing "1" and clk_disable_unprepare() when writing "0". This can have security implications, so only support it when the code has been modified to #define CLOCK_ALLOW_WRITE_DEBUGFS.
