2020-06-01sf: Drop spl_flash_get_sw_write_protJagan Teki
The get_sw_write_prot API is used to get the write-protected bits of flash by reading the status register and other wards it's API for reading register bits. 1) This kind of requirement can be achieved using existing flash operations and flash locking API calls instead of making a separate flash API. 2) Technically there is no real hardware user for this API to use in the source tree. 3) Having a flash operations API for simple register read bits also make difficult to extend the flash operations. 4) Instead of touching generic code, it is possible to have this functionality inside spinor operations in the form of flash hooks or fixups for associated flash chips. Considering all these points, this patch drops the get_sw_write_prot and associated code bases.

2020-05-29usb: dwc3: Enable AutoRetry feature in the controllerJagan Teki
By default when core sees any transaction error (CRC or overflow) it replies with terminating retry ACK (Retry=1 and Nump == 0). Enabling this Auto Retry feature in controller will make the core send a non-terminanting ACK upon such transaction errors. That is, ACK TP with Retry=1 and Nump != 0. Doing so will give controller a chance to recover from transient error conditions.

2020-05-29usb: dwc3: Add disable u2mac linestate check quirkJagan Teki
This patch adds a quirk to disable USB 2.0 MAC linestate check during HS transmit. Refer the dwc3 databook, we can use it for some special platforms if the linestate not reflect the expected line state(J) during transmission. When use this quirk, the controller implements a fixed 40-bit TxEndDelay after the packet is given on UTMI and ignores the linestate during the transmit of a token (during token-to-token and token-to-data IPGAP). On some rockchip platforms (e.g. rk3399), it requires to disable the u2mac linestate check to decrease the SSPLIT token to SETUP token inter-packet delay from 566ns to 466ns, and fix the issue that FS/LS devices not recognized if inserted through USB 3.0 HUB.

2020-05-28misc: i2c_eeprom: implement different probe test eeprom offsetEugen Hristev
Because of this commit : 5ae84860b0 ("misc: i2c_eeprom: verify that the chip is functional at probe()") at probe time, each eeprom is tested for read at offset 0. The Atmel AT24MAC402 eeprom has different mapping. One i2c slave address is used for the lower 0x80 bytes and another i2c slave address is used for the upper 0x80 bytes. Because of this basically the i2c master sees 2 different slaves. We need the upper bytes because we read the unique MAC address from this EEPROM area. However this implies that our slave address will return error on reads from address 0x0 to 0x80. To solve this, implemented an offset field inside platform data that is by default 0 (as it is used now), but can be changed in the compatible table. The probe function will now read at this offset and use it, instead of blindly checking offset 0. This will fix the regression noticed on these EEPROMs since the commit abovementioned that introduces the probe failed issue.

2020-05-28i2c: designware_i2c: Tidy up use of NULL privSimon Glass
At present we still have pre-driver-model code in this driver and it makes things a bit confusing. In particular calc_bus_speed() is called with priv as NULL if not using driver model. This results in spk_cnt and comp_param1 being read from an invalid address if not using driver model. For comp_param1 this may not cause problems if reading from addresses close to 0 happens to be allowed, as high speed is only supported by DM code. But spk_cnt is subsequently used to calculate the bus periods and so this may cause problems (e.g. on spear600 board which has not been migrated yet). Add a new parameter regs parameter to calc_bus_speed() and add more comments to this function and to _dw_i2c_set_bus_speed(), which calls it.
