clk: bcm2835: add missing release if devm_clk_hw_register fails

2020-10-29T09:11:55+00:00

[ Upstream commit f6c992ca7dd4f49042eec61f3fb426c94d901675 ] In the implementation of bcm2835_register_pll(), the allocated pll is leaked if devm_clk_hw_register() fails to register hw. Release pll if devm_clk_hw_register() fails.

clk: bcm: dvp: Select the reset framework

The DVP driver depends both on the RESET_SIMPLE driver but also on the reset framework itself. Let's make sure we have it enabled.

clk: bcm2835: Do not use prediv with bcm2711's PLLs

2020-08-03T21:26:20+00:00

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.

clk: bcm: rpi: Remove the quirks for the CPU clock

2020-06-20T00:21:18+00:00

The CPU clock has had so far a bunch of quirks to expose the clock tree properly, but since we reverted to exposing them through the MMIO driver, we can remove that code from the firmware driver.

clk: bcm2835: Don't cache the PLLB rate

2020-06-20T00:21:18+00:00

The PLLB rate will be changed through the firmware clocks drivers and will change behind this drivers' back, so we don't want to cache the rate.

2020-06-20T00:21:18+00:00

While some clock types allow for each clock to specify its own custom flags, the PLLs can't. We will need this for the PLLB, so let's add it.

Revert "clk: bcm2835: remove pllb"

2020-06-20T00:21:18+00:00

This reverts commit 2256d89333bd17b8b56b42734a7e1046d52f7fc3. Since we will be expanding the firmware clock driver, we'll need to remove the quirks to deal with the PLLB. However, we still want to expose the clock tree properly, so having that clock in the MMIO driver will allow that.
