2013-02-01ppc: Move clock fields to arch_global_dataSimon Glass
Move vco_out, cpm_clk, scc_clk, brg_clk into arch_global_data and tidy up. Leave pci_clk on its own since this should really depend only on CONFIG_PCI and not any particular chip type. Signed-off-by: Simon Glass <sjg@chromium.org>

2012-10-22poweprc/85xx: add QMan frequency info and fdt fixup.Haiying Wang
Starting from QMan3.0, the QMan clock cycle needs be exposed so that the kernel driver can use it to calculate the shaper prescaler and rate. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-10-22powerpc/mpc85xx: Add CONFIG_DDR_CLK_FREQ for corenet platformYork Sun
New corenet platforms with chassis2 have separated DDR clock inputs. Use CONFIG_DDR_CLK_FREQ for DDR clock. This patch also cleans up the logic of detecting and displaying synchronous vs asynchronous mode. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-10-22powerpc/mpc85xx: Fix core cluster PLL calculation for Chassis generation 2York Sun
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.

2012-08-23powerpc/mpc8xxx: Remove P1015 and P1016 from CPU listYork Sun

2011-09-30powerpc/mp: add support for discontiguous coresTimur Tabi
Some SOCs have discontiguously-numbered cores, and so we can't determine the valid core numbers via the FRR register any more. We define CPU_TYPE_ENTRY_MASK to specify a discontiguous core mask, and helper functions to process the mask and enumerate over the set of valid cores.

2011-04-05powerpc/85xx: Add P1021 specific QE and UEC supportHaiying Wang
P1021 has some QE pins which need to be set in pmuxcr register before using QE functions. In this patch, pin QE0 and QE3 are set for UCC1 and UCC5 in Eth mode. QE9 and QE12 are set for MII management. QE12 needs to be released after MII access because QE12 pin is muxed with LBCTL signal. Also added relevant QE support defines unique to P1021. The P1021 QE is shared on P1012, P1016, and P1025. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-04-04powerpc/85xx: Fix determining Fman freq on P1023Kumar Gala
On the P1023 the Fman freq is equivalent to the system bus freq, not 1/2 of it. Also we only have one Fman so no need for the code to deal with a second. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-04-04powerpc/85xx: Fixup determining PME, FMan freqKumar Gala
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>

There are some differences between CoreNet (P2040, P3041, P5020, P4080) and and non-CoreNet (P1017, P1023) based SoCs in what features exist and the memory maps. * Rename various immap defines to remove _CORENET_ if they are shared * Added P1023/P1017 specific memory offsets * Only setup LIODNs or LIODN related code on CORENET based SoCs (features doesn't exist on P1023/P1017) Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

2010-04-27ppc/p4080: Fix synchronous frequency calculationsSrikanth Srinivasan
When DDR is in synchronous mode, the existing code assigns sysclk frequency to DDR frequency. It should be synchronous with the platform frequency. CPU frequency is based on platform frequency in synchronous mode. Also fix: * Fixes the bit mask for DDR_SYNC (RCWSR5[184]) * Corrects the detection of synchronous mode.

2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
