* crypto/fsl: Add fixup for crypto nodeRuchika Gupta2015-01-23-0/+1
| | | | | | | | | | | Era property is added in the crypto node in device tree. Move the code to do so from arch/powerpc/mpc8xxx/fdt.c to drivers/sec/sec.c so that it can be used across arm and powerpc platforms having crypto node.

* arch/powerpc: Fix mapping of Freescale SerDes protocolsCodrin Ciubotariu2015-01-16-0/+1
| | | | | | | | | | | | | | | | The number of supported serdes protocols on Freescale SoCs has increased over time. Until now, an u64 variable have been initialized on boot with the configured protocols. However, since this number has increased (enum srds_prtcl has more than 64 values), 64 bits are no longer sufficient to hold track of all the configured protocols. This patch replaces the u64 map values with static arrays. To keep track of the number of serdes protocols, the SERDES_PRCTL_COUNT vale has been added at the end of enum srds_prtcl. This value must always be the last one. Signed-off-by: Codrin Ciubotariu <codrin.ciubotariu@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

* powerpc: mpc85xx: Add dummy gpio.h to enable CONFIG_OF_CONTROLRuchika Gupta2015-01-16-0/+15
| | | | | | | | | | | | | | | | | | | | If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled. It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. As a result, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h>. The right fix would be to split the lib/fdtdec.c to remove dependency on GPIO. This commit adds a dummy <asm/arch/gpio.h> to support OF_CONTROL for mpc85xx platform. A file mpc85xx_gpio.h exists in arch/powerpc/include/asm. The defintions in that file conflict with the ones in asm-generic/gpio.h. Hence a dummy header file has been added. This will be removed after FDT-GPIO stuff is fixed correctly.

In this mode, single onboard oscillator(DIFF_SYSCLK) can provide the reference clock (100MHz) to the following PLLs: • Platform PLL • Core PLLs • USB PLL • DDR PLL, etc The cfg_eng_use0 of porsr1 register identifies whether the SYSCLK (single-ended) or DIFF_SYSCLK (differential) is selected as the clock input to the chip. get_sys_info has been enhanced to add the diff_sysclk so that the various drivers can be made aware of ths diff sysclk configuration and act accordingly. Other changes: -single_src to ddr_refclk_sel, as it is use for checking ddr reference clock -Removed the print of single_src from get_sys_info as this will be -printed whenever somebody calls get_sys_info which is not appropriate. -Add print of single_src in checkcpu as it is called only once during initialization Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Vijay Rai <vijay.rai@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* mpc85xx: Add support for the supplement configuration unit registerTang Yuantian2014-04-22-0/+22
| | | | | | | | | | | | The supplement configuration unit (SCFG) provides chip-specific configuration and status registers for the device. It is the chip defined module for extending the device configuration unit (DCFG) module. It provides a set of CCSR registers in addition to those available in the device configuration unit. The base address for this unit is 0x0F_C000. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* powerpc/mpc85xx: Add workaround for erratum A007212York Sun2014-04-22-0/+4
| | | | | | | | | | | | | | | | | Erratum A007212 for DDR is about a runaway condition for DDR PLL oscilliator. Please refer to erratum document for detail. For this workaround to work, DDR PLL needs to be disabled in RCW. However, u-boot needs to know the expected PLL ratio. We put the ratio in a reserved field RCW[18:23]. U-boot will skip this workaround if DDR PLL ratio is set, or the reserved field is not set. Workaround for erratum A007212 applies to selected versions of B4/T4 SoCs. It is safe to apply the workaround to all versions. It is helpful for upgrading SoC without changing u-boot. In case DDR PLL is disabled by RCW (part of the erratum workaround), we need this u-boot workround to bring up DDR clock. Signed-off-by: York Sun <yorksun@freescale.com>
