Subject: [RESEND v4 2/3] clk: bcm: rpi: Handle pixel clock in firmware
Date: Mon, 29 Aug 2022 18:21:53 +0300 [thread overview]
Message-ID: <20220829152154.147250-3-iivanov@suse.de> (raw)
In-Reply-To: <20220829152154.147250-1-iivanov@suse.de>
The clk-bcm2835 handling of the pixel clock does not function
correctly when the HDMI power domain is disabled.
The firmware supports it correctly, so add it to the
firmware clock driver.
