2012-07-23net: sh_eth: add SH_ETH_TYPE_ conditionYoshihiro Shimoda
At the moment, the driver supports the following CPUs: - GETHER (Gigabit Ethernet) : SH7763, SH7734 - ETHER (Fast Ethernet) : SH7724, SH7757 And the driver had the following "#if": #if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734) #if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724) - Those are for GETHER #if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757) - This is for ETHER So, for clean up the code, this patch adds SH_ETH_TYPE_GETHER and SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if". Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>

2012-07-19net: fec_mxc: Fix MDC for xMIIbenoit.thebaudeau@advans

2012-07-19net: fec_mxc: Fix setting of RCR for xMIIbenoit.thebaudeau@advans
At least on i.MX25, the RMII mode did not work, which is fixed by this patch. The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set it accordingly. According to the xMII and 7-wire (aka GPSI) standards, full duplex should be available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may support full duplex for 7-wire too, but the reference manual does not say that, so avoid an invalid assumption. Actually, the choice between half and full duplex also depends on the endpoint/switch/repeater configuration, so a config option could be added for that, but there has been no need for it so far.

2012-07-11net/designware: Consecutive writes to the same register to be avoidedDinh Nguyen
This commit is an add-on to f6c4191f. There are a few registers where consecutive writes to the same location should be avoided or have a delay. According to Synopsys, here is a list of the registers and bit(s) where consecutive writes should be avoided or a delay is required: DMA Registers: Register 0 Bit 7 Register 6 All bits except for 24, 16-13, 2-1. GMAC Registers: Registers 0-3 All bits Registers 6-7 All bits Register 10 All bits Register 11 All bits except for 5-6. Registers 16-47 All bits Register 48 All bits except for 18-16, 14.

2012-07-11mxs-i2c: Fix internal address byte orderTorsten Fleischer
Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory. These devices require that the high byte of the internal address has to be written first.

Other then being very weird, this code was also wrong. For example, say I set speed to 100K. I'll read back the speed as 85937. But the speed is really 85937.5, so we I reset the speed to 85937, I'll get 73660.7. After a couple of transactions my speed is now exactly 68750 so it will remain there.

2012-07-07net: Multiple updates/enhancements to designware.cStefan Roese
This patch adds the following changes to designware ethernet driver found on the ST SPEAr SoC: - Don't init MAC & PHY upon startup. This causes a delay, waiting for the auto negotiation to complete. And we don't want this delay to always happen. Especially not on platforms where ethernet is not used at all (e.g. booting via flash). Instead postpone the MAC / PHY configuration to the stage, where ethernet is first used. - Add possibility for board specific PHY init code. This is needed for example on the X600 board, where the Vitesse PHY needs to be configured for GMII mode. This board specific PHY init is done via the function designware_board_phy_init(). And this driver now adds a weak default which can be overridden by board code. - Use common functions miiphy_speed() & miiphy_duplex() to read link status from PHY. - Print status and progress of auto negotiation. - Print link status (speed, dupex) upon first usage.

2012-07-07Revert "I2C: OMAP: detect more devices when probing an i2c bus"Tom Rini
This reverts commit 0e57968a215d1b9d271f3fa5bebeddeaea0c8075. The short version of the original commit is that some i2c devices cannot be probed via read as they NAK the first cycle, so try and probe via a write that we abort before it writes to the device. This however is not allowed by the TRM for any of these parts. The section on I2C_CON (table 17-35 I2C_CON for am/dm37x for example) says you must not change the register while STT has been set. On these parts, the unpredictable behavior that the chip exhibits is not problematic. On OMAP4 however it results in the chip being in a bad state: Panda # i2c probe Valid chip addresses: 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F Panda # i2c md 50 0 timed out in wait_for_pin: I2C_STAT=0 I2C read: I/O error Error reading the chip.
