* powerpc/85xx: Enhance get_sys_info() to check clocking modevijay rai2014-04-22-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | T1040 and it's variants provide "Single Oscillator Source" Reference Clock Mode. 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>
* powerpc/mpc85xx: Add workaround for erratum A007212York Sun2014-04-22-0/+7
| | | | | | | | | | | | | | | | | 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>

* powerpc/mpc85xx: Add support for single source clockingPriyanka Jain2014-01-02-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | Single-source clocking is new feature introduced in T1040. In this mode, a single differential clock is supplied to the DIFF_SYSCLK_P/N inputs to the processor, which in turn is used to supply clocks to the sysclock, ddrclock and usbclock. So, both ddrclock and syclock are driven by same differential sysclock in single-source clocking mode whereas in normal clocking mode, generally separate DDRCLK and SYSCLK pins provides reference clock for sysclock and ddrclock DDR_REFCLK_SEL rcw bit is used to determine DDR clock source -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in normal clocking mode by DDR_Reference clock -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in single source clocking mode by DIFF_SYSCLK Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

* powerpc/mpc85xx: Fix core cluster PLL calculation for Chassis generation 2York Sun2012-10-22-10/+128
| | | | | | | | | | | | | | | | | | Corenet based SoCs have different core clocks starting from Chassis generation 2. Cores are organized into clusters. Each cluster has up to 4 cores sharing same clock, which can be chosen from one of three PLLs in the cluster group with one of the devisors /1, /2 or /4. Two clusters are put together as a cluster group. These two clusters share the PLLs but may have different divisor. For example, core 0~3 are in cluster 1. Core 4~7 are in cluster 2. Core 8~11 are in cluster 3 and so on. Cluster 1 and 2 are cluster group A. Cluster 3 and 4 are in cluster group B. Cluster group A has PLL1, PLL2, PLL3. Cluster group B has PLL4, PLL5. Core 0~3 may have PLL1/2, core 4~7 may have PLL2/2. Core 8~11 may have PLL4/1. PME and FMan blocks can take different PLLs, configured by RCW.

| | | | | | | | | | | | | | | | | | | | | | On CoreNet based SoCs (P2040, P3041, P4080, P5020) we have some additional rules to determining the various frequencies that PME & FMan IP blocks run at. We need to take into account: * Reduced number of Core Complex PLL clusters * HWA_ASYNC_DIV (allows for /2 or /4 options) On P2040/P3041/P5020 we only have 2 Core Complex PLLs and in such SoCs the PME & FMan blocks utilize the second Core Complex PLL. On SoCs like p4080 with 4 Core Complex PLLs we utilize the third Core Complex PLL for PME & FMan blocks. On P2040/P3041/P5020 we have the added feature that we can divide the PLL down further by either /2 or /4 based on HWA_ASYNC_DIV. On P4080 this options doesn't exist, however HWA_ASYNC_DIV field in RCW should be set to 0 and this gets a backward compatiable /2 behavior. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
