From: Anson Huang Date: Fri, 7 Dec 2018 06:05:36 +0000 (+0000) Subject: clocksource/drivers/timer-imx-tpm: Specify clock name for timer-of X-Git-Tag: v5.0-rc1~168^2~1^2~7 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4f352d1fc5a8d3220e29766a26172eff34867014;p=thirdparty%2Fkernel%2Flinux.git clocksource/drivers/timer-imx-tpm: Specify clock name for timer-of i.MX TPM needs "ipg" clock for register access and "per" clock for timer function, the driver gets "ipg" clock by searching the clock name, but timer-of initialization will get first clock in device tree TPM node since no clock name specified in of_clk, that means the "per" clock MUST be the first clock entry in device tree TPM node, this patch specifies clock name for of_clk to avoid this restriction, it makes TPM driver work properly with different sequence of clock entries in device tree TPM node.
