[PATCH 3/7] pistachio: Make patches and configuration apply on to of 5.4
Hauke Mehrtens
hauke at hauke-m.de
Sat Aug 15 14:06:52 EDT 2020
This refreshes the patches, removes patches already applied upstream and
removes the SPI NAND framework to use the upstream version.
In addition it also refreshes the kernel configuration.

-Subject: spi: img-spfi: set device select bits for SPFI port state
-
-Even if the chip select line is not controlled by the SPFI
-hardware, the device select bits need to be set to specify
-the chip select line in use for the hardware to know what
-parameters to use for the current transfer.

-Subject: clockevents: Retry programming min delta up to 10 times
-
-Under virtualisation it is possible to get unexpected latency during a
-clockevent device's set_next_event() callback which can make it return
--ETIME even for a delta based on min_delta_ns.
-
-The clockevents_program_min_delta() implementation for
-CONFIG_GENERIC_CLOCKEVENTS_MIN_ADJUST=n doesn't handle retries when this
-happens, nor does clockevents_program_event() or its callers when force
-is true (for example hrtimer_reprogram()). This can result in hangs
-until the clock event device does a full period.
-
-It isn't appropriate to use MIN_ADJUST in this case as occasional
-hypervisor induced high latency will cause min_delta_ns to quickly
-increase to the maximum.
-Instead, borrow the retry pattern from the MIN_ADJUST case, but without
-making adjustments. We retry up to 10 times before giving up.

-Subject: mtd: nand: Check length of ID before reading bits per cell
-
-The table-based NAND identification currently reads the number
-of bits per cell from the 3rd byte of the extended ID. This is done
-for the so-called 'full ID' devices; i.e. devices that have a known
-length ID.
-
-However, if the ID length is shorter than three, there's no 3rd byte,
-and so it's wrong to read the bits per cell from there. Fix this by
-adding a check for the ID length.

-
-Add a new framework, to support SPI NAND devices. The framework registers
-a NAND chip and handles the generic SPI NAND protocol, calling device-specific
-hooks for each SPI NAND command.
-
-The following is the stack design, from userspace to hardware. This commit
-adds the "SPI NAND core" layer.

-From: Ezequiel Garcia <ezequiel.garcia at imgtec.com>
-Date: Tue, 28 Feb 2017 10:37:24 +0000
-Subject: mtd: spi-nand: Support Gigadevice GD5F
-
-This commit uses the recently introduced SPI NAND framework to support
-the Gigadevice GD5F serial NAND device.
-
-The current support includes:
-
- * Page read and page program operations (using on-die ECC)
- * Page out-of-band read
- * Erase
- * Reset
- * Device status retrieval
- * Device ID retrieval
-
-(based on http://lists.infradead.org/pipermail/linux-mtd/2014-December/056769.html)
