This property does not describe very well its purpose: it describes the ECC engine type. Deprecate it in favor of nand-ecc-engine which points to either the NAND part itself in case of on-die ECC, or to the parent node in case of an integrated ECC engine in the NAND controller (previously referred as "hardware") or to another node in case of an external controller. Other "modes" (none/software) are achieved with the new nand-use-soft-ecc-engine and nand-no-ecc-engine properties.

2020-12-10file: Replace fcheck_files with files_lookup_fd_rcuEric W. Biederman1-3/+3
This change renames fcheck_files to files_lookup_fd_rcu. All of the remaining callers take the rcu_read_lock before calling this function so the _rcu suffix is appropriate. This change also tightens up the debug check to verify that all callers hold the rcu_read_lock. All callers that used to call files_check with the files->file_lock held have now been changed to call files_lookup_fd_locked. This change of name has helped remind me of which locks and which guarantees are in place helping me to catch bugs later in the patchset. The need for better names became apparent in the last round of discussion of this set of changes[1].

2020-12-10dt-bindings: remoteproc: Add binding doc for PRU cores in the PRU-ICSSSuman Anna1-0/+214
The Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS or simply PRUSS) on various TI SoCs consists of dual 32-bit RISC cores (Programmable Real-Time Units, or PRUs) for program execution. The K3 AM65x amd J721E SoCs have the next generation of the PRU-ICSS IP, commonly called ICSSG. The ICSSG IP on AM65x SoCs has two PRU cores, two auxiliary custom PRU cores called Real Time Units (RTUs). The K3 AM65x SR2.0 and J721E SoCs have a revised version of the ICSSG IP, and include two additional custom auxiliary PRU cores called Transmit PRUs (Tx_PRUs). This patch adds the bindings for these PRU cores. The binding covers the OMAP architecture SoCs - AM33xx, AM437x and AM57xx; Keystone 2 architecture based 66AK2G SoC; and the K3 architecture based SoCs - AM65x and J721E. The Davinci based OMAPL138 SoCs will be covered in a future patch.

Convert the device tree bindings for tm2-touchkey to the YAML format. While we're at it, clarify the descriptions a bit to make it clear that this driver can be used for many different MCUs that all implement a similar I2C protocol. Depending on the MCU the voltage requirements may be different, on some devices the controller uses 2.2V, 2.8V or even 3.3V for vcc-supply instead of 1.8V.

2020-12-09dt-bindings: net: nfc: s3fwrn5: Change I2C interrupt trigger typeBongsu Jeon1-1/+1
Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING for stable NFC I2C interrupt handling. Samsung's NFC Firmware sends an i2c frame as below. 1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c frame to send. 2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the GPIO low. NFC driver's i2c interrupt handler would be called in the abnormal case as the NFC FW task of number 2 is delayed because of other high priority tasks. In that case, NFC driver will try to receive the i2c frame but there isn't any i2c frame to send in NFC. It would cause an I2C communication problem. This case would hardly happen. But, I changed the interrupt as a defense code. If Driver uses the TRIGGER_RISING instead of the LEVEL trigger, there would be no problem even if the NFC FW task is delayed.

2020-12-09docs: update requirements to install six moduleJaeSang Yoo1-0/+1
On the update of Sphinx version to 2.4.4, the "six" library won't be installed automatically. (which is required by kfigure.py) Main reason of this issue were occurred by the requirements changed from the sphinx library. In Sphinx v1.7.9, six was listed on the install_requires, but it has been removed since 2.x The kfigure.py uses six library explicitly, adding six to requirements.txt seems reasonable Signed-off-by: JaeSang Yoo <jsyoo5b@gmail.com> Reviewed-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/20201208014628.GA1361@JSYoo5B-Base.localdomain Signed-off-by: Jonathan Corbet <corbet@lwn.net>
