Message-Id: <20180427001745.4116-9-david@lechnology.com> Date: Thu, 26 Apr 2018 19:17:26 -0500 From: David Lechner <david@...hnology.com> To: linux-clk@...r.kernel.org, devicetree@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: Michael Turquette <mturquette@...libre.com>, Stephen Boyd <sboyd@...eaurora.org>, Rob Herring <robh+dt@...nel.org>, Mark Rutland <mark.rutland@....com>, Sekhar Nori <nsekhar@...com>, Kevin Hilman <khilman@...nel.org>, Bartosz Golaszewski <bgolaszewski@...libre.com>, Adam Ford <aford173@...il.com>, linux-kernel@...r.kernel.org, David Lechner <david@...hnology.com> Subject: [PATCH v9 08/27] ARM: davinci: dm365: add new clock init using common clock framework This adds the new board-specific clock init in mach-davinci/dm365.c using the new common clock framework drivers. The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Also clean up the #includes since we are adding some here. Signed-off-by: David Lechner <david@...hnology.com> --- v9 changes: - register PLL1 and PSC in dm365_init_time() instead of as platform device so that we get the correct timer0 clock for davinci_timer_init() - Fixed size of PLL memory block v8 changes: - none v7 changes: - add clock platform device declarations - register platform devices instead of registering clocks directly - add davinci prefix to commit description v6 changes: - add blank lines between function calls arch/arm/mach-davinci/board-dm365-evm.c | 2 + arch/arm/mach-davinci/davinci.h | 1 + arch/arm/mach-davinci/dm365.c | 56 +++++++++++++++++++------ 3 files changed, 47 insertions(+), 12 deletions(-) diff --git a/arch/arm/mach-davinci/board-dm365-evm.c b/arch/arm/mach-davinci/board-dm365-evm.c index 0ac085b58a2b..36b69a131cfa 100644 --- a/arch/arm/mach-davinci/board-dm365-evm.c +++ b/arch/arm/mach-davinci/board-dm365-evm.c @@ -741,6 +741,8 @@ static __init void dm365_evm_init(void) { int ret; + dm365_register_clocks(); + ret = dm365_gpio_register(); if (ret) pr_warn("%s: GPIO init failed: %d\n", __func__, ret); diff --git a/arch/arm/mach-davinci/davinci.h b/arch/arm/mach-davinci/davinci.h index c2c634b6578e..a799b5266d4b 100644 --- a/arch/arm/mach-davinci/davinci.h +++ b/arch/arm/mach-davinci/davinci.h @@ -94,6 +94,7 @@ int dm355_gpio_register(void); /* DM365 function declarations */ void dm365_init(void); void dm365_init_time(void); +void dm365_register_clocks(void); void dm365_init_asp(void); void dm365_init_vc(void); void dm365_init_ks(struct davinci_ks_platform_data *pdata); diff --git a/arch/arm/mach-davinci/dm365.c b/arch/arm/mach-davinci/dm365.c index 871372a59da8..76de426a0e41 100644 --- a/arch/arm/mach-davinci/dm365.c +++ b/arch/arm/mach-davinci/dm365.c @@ -12,32 +12,38 @@ * of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
