* ENGR00331706-3 imx: mx6: Change the get_ipg_per_clk for OSC 24Mhz sourceYe.Li2014-09-18-0/+4
| | | | | | | For MX6SL and MX6SX, the perclk can come from OSC 24Mhz source. Fix the get_ipg_per_clk function to support it. Signed-off-by: Ye.Li <B37916@freescale.com>
* ENGR00330792 imx: mx6: Merge anatop registers to CCM structureYe.Li2014-09-10-14/+7
| | | | | | | | | | THe anatop registers structure is duplicated with CCM structure at PLL fields. Since we are suggested not to use the name "anatop" any longer, merge the anatop registers to the CCM structure "mxc_ccm_reg" and use CCM to replace anatop. Signed-off-by: Ye.Li <B37916@freescale.com>
* ENGR00323255 Fixed QSPI randomly access timeout issueAllen Xu2014-08-29-16/+22
| | | | | | | | | | | | | | | | The QSPI clock rate was set without disabling the clock gate, the randomly glitch may mess up the clock and there will be no clock output, when kernel boot up the QSPI access will fail. To debug this issueon i.MX6SX SDB, changed the u-boot bootscript to 'sf probe; reset' to keep rebooting, the issue can be reproduced in 20 mins, set clock out register in CCM and measured TP86, found there is no clock ouput. To fix this bug, disable clock gate before changing clock rate. NOTICE: QSPI2 and GPMI_BCH_INPUT_GPMI_IO share the same clock gate, need to disable both of them.

* ENGR00325255 pcie:enable pcie support on imx6sx sdRichard Zhu2014-07-31-6/+26
| | | | | | | | | | | | | | Enable pcie support in uboot on imx6sx sd boards - enable_pcie_clock should be call before ssp_en is set, since that ssp_en control the phy_ref clk gate, turn on it after the source of the pcie clks are stable. - add debug info - add rx_eq of gpr12 on imx6sx - there are random link down issue on imx6sx. It's pcie ep reset issue. solution:reset ep, then retry link can fix it. Signed-off-by: Richard Zhu <r65037@freescale.com>

* ENGR00315894-54 iMX6SX/SL: Modify SOC to support two ENETYe.Li2014-06-17-3/+40
| | | | | | | | | | | | | | | | | | | | | iMX6SX has different enet system clocks with iMX6SL, and has two ENET controllers. So update clocks and soc APIs accordingly to support this features. 1. Modify the clock API "enable_enet_clock" to enable enet system clock for enet controllers. 2. Enet RGMII TX clock source may come from external or internal PLL. By default, use the external phy CLK_25M output as TX clock source. When using internal PLL as source, the function enable_fec_anatop_clock must be called to enable clock for each enet controller. 3. Modify the MAC address function "imx_get_mac_from_fuse" to get either ENET MAC address. 4. Add configuration "CONFIG_FEC_MXC_25M_REF_CLK" to enable ENET 25Mhz reference clock. 5. Modify imx6slevk BSP to fit the new APIs. Signed-off-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Ye.Li <B37916@freescale.com>

* ARM: imx6: fix wrong fec clkMarkus Niebel2014-02-11-1/+1
| | | | | | | | | | imx_get_fecclk() returns enet_ref instead of ipg. Since the clock is used to calculate the prescaler for the MDIO interface wrong values can be calculated. Tested on a custom MX6S board with 100MBit interface Signed-off-by: Markus Niebel <Markus.Niebel@tqs.de>
* ARM: mx6: Add PCI express clock configurationMarek Vasut2014-01-26-10/+65
| | | | | | | | | | | | | | | | Split the SATA clock enabling function and add PCI express clock enabling function. The SATA clock enabling function starts up the 100MHz SATA reference PLL in ENET_PLL register, but the code can be re-used to enable the 125MHz PCIe reference in ENET_PLL, so pull this code into separate function. Moreover, add the PCIe clock enabling code.

| | | | | | | | | | The enable_fec_anatop_clock method should be available for all MX6 variant as it is not MX6 SoloLite specific.

* mx6: clock: Fix the calculation of PLL_ENET frequencyFabio Estevam2013-12-17-1/+1
| | | | | | | | | | | | | | | | According to the mx6 quad reference manual, the DIV_SELECT field of register CCM_ANALOG_PLL_ENETn has the following meaning: "Controls the frequency of the ethernet reference clock. - 00 - 25MHz - 01 - 50MHz - 10 - 100MHz - 11 - 125MHz" Current logic does not handle the 25MHz case correctly, so fix it.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
