* ENGR00163704: MX5X: add i2c recovery function in board_lateinit.Zhang Jiejing2011-12-16-0/+562
| | | | | | | | | | | | | | | | | | This patch add a i2c bus recovery function, the i2c bus busy because some device pull down the I2C SDA line. This happens when Host is reading some byte from slave, and then host is reset/reboot. Since in this case, device is controlling i2c SDA line, the only thing host can do this give the clock on SCL and sending NAK, and STOP to finish this transaction. To fix this issue: when we found SDA is low, we generate 8 clock to let device send data, then send a NAK, and STOP to finish this I2C transaction , after this the clock will be clean.

* ENGR00162491 Android: MX53_SMD: enter recovery mode by key.Zhang Jiejing2011-12-16-1/+16
| | | | | | | | | | | Implement a key press check on recovery mode check. User can press Vol- key to enter recovery mode when boot. Idealy, should be a combo key press together, but on SMD it only can Vol+ or Vol- but it can't press together. More usuful for user and less bug.

* ENGR00156389: turn off child clocks before reconfigure perclk_rootZhang Jiejing2011-12-16-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | In addition to ensuring that PERCLK remains at least 2.5 times slower than the AHB clock, certain steps need to be followed to ensure robust operation of PERCLK when reconfiguring the PERCLK clock source. To properly configure the PERCLK clock source, the following steps are required: 1.In the CCGR registers, gate the clocks to all PERCLK-dependent modules. 2.Select the desired input clock for the PERCLK root clock (to be either source from the peripherals main source clock or the lp_apm clock source). Refer to the CMCBR register, perclk_lp_apm_sel bit. 3.Configure the perclk_pred1, perclk_pred2, and perclk_podf dividers to the desired setting. Refer to the CBCDR register for details. 4.In the CCGR registers, enable the desired clocks for the PERCLK-dependent module clocks. Certain steps are required to reconfigure perclk_root. If don't follow these steps, GPT timer may stop and the kernel stops at " "Calibrating delay loop". Signed-off-by: Terry Lv <r65388@freescale.com>

* ENGR00156098 mx53_smd/mx53_loco: DA9053 I2C SDA stuck low issue on bootupWayne Zou2011-09-13-2/+204
| | | | | | | | | | | | | | | | For DA9053 I2C SDA stuck low issue: the I2C block in DA9053 may not correctly receive a Power On Reset and device is in unknown state during start-up. The only way to get the chip into known state before any communication with the Chip via I2C is to dummy clock the I2C and bring it in a state where I2C can communicate. Dialog suggested to provide 9 clock on SCL. Dialog don't know the exact reason for the fault and assume it is because some random noise or spurious behaviour. This has to been done in host platform specific I2C driver during start-up when the I2C is being configured at platform level to supply with dummy 9 clock on SCL. Dialog I2C driver has no control to provide dummy 9 clock on SCL. Signed-off-by: Wayne Zou <b36644@freescale.com>
* ENGR00155284 mx53_smd: move I2C access to board_init_late for system hang issueWayne Zou2011-09-06-9/+12
| | | | | | | | | | | | MX53 SMD hangs if reset many times with lower possibility. If doing I2C access in early time, I2C may cause system hangs. So moving I2C access to late phase to make system hang issue disappear. QA Test result: QA raised 6 full rounds of CTS one-round test Totally ran for 6 rounds about 27 hours, reboot for 56*6=336 times, no reboot failure occurred.

* ENGR00152755 MX6 Switch DRAM init script from plugin to DCD for emmc fastbootAnish Trivedi2011-07-06-265/+146
| | | | | | | | | | | | | | | | | ROM requires DCD table instead of plugin to initialize DRAM if emmc fastboot mode is to be used. Therefore, switched the DRAM script from plugin to DCD table. The DCD table created is based on the following RVD script: Arik_init_DDR3_528MHz_002.inc found at http://compass.freescale.net/livelink/livelink?func=ll&objId=222928845 When fastboot mode is used by ROM, the MMC_BOOT register of USDHC does not get reset when RSTA bit is set by uboot driver. Therefore, need to write 0 to it manually during driver init. This brings USDHC out of fastboot mode, allowing normal communication with emmc to proceed in uboot. Changed comments for DLL delay to be more accurate. Signed-off-by: Anish Trivedi <anish@freescale.com>

To make it works on sabreauto, need do following changes: 1. rework phy to output 125M clock from CLK_25M signal, and the 125M clock input to SoC as reference clock to generate RGMII_TXC clock. 2. Enable TXC delay in PHY debug register. 3. set ENET working in RMII mode. 4. set ENET working at 1000M or 100M/10M. 5. set ENET TX fifo to maximum to avoid underrun error. 6. force AR8031 PHY working at 100M Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Zeng Zhaoming <b32542@freescale.com>
