From: Arnd Bergmann Date: Fri, 15 May 2015 15:40:15 +0000 (+0200) Subject: Merge tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux into next/soc X-Git-Tag: v4.2-rc1~100^2~33 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7448adca9361b4ad97614a08c487e215f1990ad7;hp=e3abcb25d2aec8411ec1b197712b1085df5bfee3;p=karo-tx-linux.git Merge tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux into next/soc Merge "pxa changes for v4.2 cycle" from Robert Jarzmik: The main and only feature is the conversion of all pxa variants to clock framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards. This should be a disruptive cycle in the normally quiet pxa history, as the change can break any platform, and the test were performed on only 4 boards (lubbock, zylonite, mioa701, cm-x300). * tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux: ARM: pxa: Constify irq_domain_ops ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk framework ARM: pxa: convert eseries to clock framework ARM: pxa: Transition pxa25x and pxa27x to clk framework ARM: pxa: pxa27x skip default device initialization with DT clk: pxa: add missing pxa27x clocks for Irda and sa1100-rtc ARM: pxa: move gpio11 clock to board files ARM: pxa: change clocks init sequence --- diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index b2e0d98894d3..7cd23bb03244 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -606,6 +606,7 @@ config ARCH_PXA select ARCH_REQUIRE_GPIOLIB select ARM_CPU_SUSPEND if PM select AUTO_ZRELADDR + select COMMON_CLK select CLKDEV_LOOKUP select CLKSRC_MMIO select CLKSRC_OF diff --git a/arch/arm/mach-pxa/Makefile b/arch/arm/mach-pxa/Makefile index 4087d334ecdf..2ceed407eda9 100644 --- a/arch/arm/mach-pxa/Makefile +++ b/arch/arm/mach-pxa/Makefile @@ -3,16 +3,15 @@ # # Common support (must be linked before board specific support) -obj-y += clock.o devices.o generic.o irq.o \ - reset.o +obj-y += devices.o generic.o irq.o reset.o obj-$(CONFIG_PM) += pm.o sleep.o standby.o # Generic drivers that other drivers may depend upon # SoC-specific code -obj-$(CONFIG_PXA25x) += mfp-pxa2xx.o clock-pxa2xx.o pxa2xx.o pxa25x.o -obj-$(CONFIG_PXA27x) += mfp-pxa2xx.o clock-pxa2xx.o pxa2xx.o pxa27x.o -obj-$(CONFIG_PXA3xx) += mfp-pxa3xx.o clock-pxa3xx.o pxa3xx.o smemc.o pxa3xx-ulpi.o +obj-$(CONFIG_PXA25x) += mfp-pxa2xx.o pxa2xx.o pxa25x.o +obj-$(CONFIG_PXA27x) += mfp-pxa2xx.o pxa2xx.o pxa27x.o +obj-$(CONFIG_PXA3xx) += mfp-pxa3xx.o pxa3xx.o smemc.o pxa3xx-ulpi.o obj-$(CONFIG_CPU_PXA300) += pxa300.o obj-$(CONFIG_CPU_PXA320) += pxa320.o obj-$(CONFIG_CPU_PXA930) += pxa930.o diff --git a/arch/arm/mach-pxa/clock-pxa2xx.c b/arch/arm/mach-pxa/clock-pxa2xx.c deleted file mode 100644 index 9ee2ad6a0a07..000000000000 --- a/arch/arm/mach-pxa/clock-pxa2xx.c +++ /dev/null @@ -1,55 +0,0 @@ -/* - * linux/arch/arm/mach-pxa/clock-pxa2xx.c - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. - */ - -#include -#include -#include -#include -#include - -#include - -#include "clock.h" - -void clk_pxa2xx_cken_enable(struct clk *clk) -{ - CKEN |= 1 << clk->cken; -} - -void clk_pxa2xx_cken_disable(struct clk *clk) -{ - CKEN &= ~(1 << clk->cken); -} - -const struct clkops clk_pxa2xx_cken_ops = { - .enable = clk_pxa2xx_cken_enable, - .disable = clk_pxa2xx_cken_disable, -}; - -#ifdef CONFIG_PM -static uint32_t saved_cken; - -static int pxa2xx_clock_suspend(void) -{ - saved_cken = CKEN; - return 0; -} - -static void pxa2xx_clock_resume(void) -{ - CKEN = saved_cken; -} -#else -#define pxa2xx_clock_suspend NULL -#define pxa2xx_clock_resume NULL -#endif - -struct syscore_ops pxa2xx_clock_syscore_ops = { - .suspend = pxa2xx_clock_suspend, - .resume = pxa2xx_clock_resume, -}; diff --git a/arch/arm/mach-pxa/clock-pxa3xx.c b/arch/arm/mach-pxa/clock-pxa3xx.c deleted file mode 100644 index d4e9499832dc..000000000000 --- a/arch/arm/mach-pxa/clock-pxa3xx.c +++ /dev/null @@ -1,212 +0,0 @@ -/* - * linux/arch/arm/mach-pxa/clock-pxa3xx.c - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. - */ - -#include -#include -#include -#include -#include - -#include -#include - -#include "clock.h" - -/* Crystal clock: 13MHz */ -#define BASE_CLK 13000000 - -/* Ring Oscillator Clock: 60MHz */ -#define RO_CLK 60000000 - -#define ACCR_D0CS (1 << 26) -#define ACCR_PCCE (1 << 11) - -/* crystal frequency to HSIO bus frequency multiplier (HSS) */ -static unsigned char hss_mult[4] = { 8, 12, 16, 24 }; - -/* - * Get the clock frequency as reflected by CCSR and the turbo flag. - * We assume these values have been applied via a fcs. - * If info is not 0 we also display the current settings. - */ -unsigned int pxa3xx_get_clk_frequency_khz(int info) -{ - unsigned long acsr, xclkcfg; - unsigned int t, xl, xn, hss, ro, XL, XN, CLK, HSS; - - /* Read XCLKCFG register turbo bit */ - __asm__ __volatile__("mrc\tp14, 0, %0, c6, c0, 0" : "=r"(xclkcfg)); - t = xclkcfg & 0x1; - - acsr = ACSR; - - xl = acsr & 0x1f; - xn = (acsr >> 8) & 0x7; - hss = (acsr >> 14) & 0x3; - - XL = xl * BASE_CLK; - XN = xn * XL; - - ro = acsr & ACCR_D0CS; - - CLK = (ro) ?
