From e58cd453d58b20c6a6f34d3591640aa19aa14d25 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Fri, 4 Feb 2022 15:57:50 +0200 Subject: at91: add kernel support for sama7g5 soc Add kernel support for SAMA7G5 by back-porting mainline kernel patches. Among SAMA7G5 features could be remembered: - ARM Cortex-A7 - double data rate multi-port dynamic RAM controller supporting DDR2, DDR3, DDR3L, LPDDR2, LPDDR3 up to 533MHz - peripherals for audio, video processing - 1 gigabit + 1 megabit Ethernet controllers - 6 CAN controllers - trust zone support - DVFS for CPU - criptography IPs Signed-off-by: Claudiu Beznea --- .../191-i2c-at91-remove-define-CONFIG_PM.patch | 81 ++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 target/linux/at91/patches-5.10/191-i2c-at91-remove-define-CONFIG_PM.patch (limited to 'target/linux/at91/patches-5.10/191-i2c-at91-remove-define-CONFIG_PM.patch') diff --git a/target/linux/at91/patches-5.10/191-i2c-at91-remove-define-CONFIG_PM.patch b/target/linux/at91/patches-5.10/191-i2c-at91-remove-define-CONFIG_PM.patch new file mode 100644 index 0000000000..bbdf5bcbac --- /dev/null +++ b/target/linux/at91/patches-5.10/191-i2c-at91-remove-define-CONFIG_PM.patch @@ -0,0 +1,81 @@ +From 023a6b46536dce41f2c5a7425826fc4da4509b8f Mon Sep 17 00:00:00 2001 +From: Claudiu Beznea +Date: Mon, 5 Jul 2021 15:15:16 +0300 +Subject: [PATCH 191/247] i2c: at91: remove #define CONFIG_PM + +Remove #define CONFIG_PM and use __maybe_unused for PM functions and +pm_ptr() for PM ops. + +Signed-off-by: Claudiu Beznea +Reviewed-by: Codrin Ciubotariu +Signed-off-by: Wolfram Sang +--- + drivers/i2c/busses/i2c-at91-core.c | 17 +++++------------ + 1 file changed, 5 insertions(+), 12 deletions(-) + +diff --git a/drivers/i2c/busses/i2c-at91-core.c b/drivers/i2c/busses/i2c-at91-core.c +index e14edd236108..9f3c3e8e8011 100644 +--- a/drivers/i2c/busses/i2c-at91-core.c ++++ b/drivers/i2c/busses/i2c-at91-core.c +@@ -286,9 +286,7 @@ static int at91_twi_remove(struct platform_device *pdev) + return 0; + } + +-#ifdef CONFIG_PM +- +-static int at91_twi_runtime_suspend(struct device *dev) ++static int __maybe_unused at91_twi_runtime_suspend(struct device *dev) + { + struct at91_twi_dev *twi_dev = dev_get_drvdata(dev); + +@@ -299,7 +297,7 @@ static int at91_twi_runtime_suspend(struct device *dev) + return 0; + } + +-static int at91_twi_runtime_resume(struct device *dev) ++static int __maybe_unused at91_twi_runtime_resume(struct device *dev) + { + struct at91_twi_dev *twi_dev = dev_get_drvdata(dev); + +@@ -308,7 +306,7 @@ static int at91_twi_runtime_resume(struct device *dev) + return clk_prepare_enable(twi_dev->clk); + } + +-static int at91_twi_suspend_noirq(struct device *dev) ++static int __maybe_unused at91_twi_suspend_noirq(struct device *dev) + { + if (!pm_runtime_status_suspended(dev)) + at91_twi_runtime_suspend(dev); +@@ -316,7 +314,7 @@ static int at91_twi_suspend_noirq(struct device *dev) + return 0; + } + +-static int at91_twi_resume_noirq(struct device *dev) ++static int __maybe_unused at91_twi_resume_noirq(struct device *dev) + { + struct at91_twi_dev *twi_dev = dev_get_drvdata(dev); + int ret; +@@ -342,11 +340,6 @@ static const struct dev_pm_ops at91_twi_pm = { + .runtime_resume = at91_twi_runtime_resume, + }; + +-#define at91_twi_pm_ops (&at91_twi_pm) +-#else +-#define at91_twi_pm_ops NULL +-#endif +- + static struct platform_driver at91_twi_driver = { + .probe = at91_twi_probe, + .remove = at91_twi_remove, +@@ -354,7 +347,7 @@ static struct platform_driver at91_twi_driver = { + .driver = { + .name = "at91_i2c", + .of_match_table = of_match_ptr(atmel_twi_dt_ids), +- .pm = at91_twi_pm_ops, ++ .pm = pm_ptr(&at91_twi_pm), + }, + }; + +-- +2.32.0 + -- cgit v1.2.3
