Message-Id: <20180427001745.4116-12-david@lechnology.com> Date: Thu, 26 Apr 2018 19:17:29 -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 11/27] ARM: davinci: da8xx: add new USB PHY clock init using common clock framework This adds the new USB PHY clock init in mach-davinci/usb-da8xx.c using the new common clock framework drivers. The #ifdefs are needed to prevent compile errors until the entire ARCH_DAVINCI is converted. Signed-off-by: David Lechner <david@...hnology.com> --- v9 changes: - none v8 changes: - rebased on "ARM: davinci: DA8XX: fix oops in USB PHY driver due to stack allocated platform platform_data" v7 changes: - register platform device instead of registering clocks directly - USB PHY clocks now treated as single device instead of registering them separately v6 changes: - rename stuff to match changes in "clk: davinci: New driver for TI DA8XX USB PHY clocks" - take advantage of syscon lookup changes in "mfd: syscon: Add syscon_register() function" arch/arm/mach-davinci/board-da830-evm.c | 8 ++++++- arch/arm/mach-davinci/board-omapl138-hawk.c | 9 +++++-- arch/arm/mach-davinci/da8xx-dt.c | 8 ++++++- arch/arm/mach-davinci/include/mach/da8xx.h | 1 + arch/arm/mach-davinci/usb-da8xx.c | 26 +++++++++++++++++++-- 5 files changed, 46 insertions(+), 6 deletions(-) diff --git a/arch/arm/mach-davinci/board-da830-evm.c b/arch/arm/mach-davinci/board-da830-evm.c index 3973124e5f1d..6e77c458ec8e 100644 --- a/arch/arm/mach-davinci/board-da830-evm.c +++ b/arch/arm/mach-davinci/board-da830-evm.c @@ -110,6 +110,12 @@ static __init void da830_evm_usb_init(void) { int ret;
