mtd: lpddr: Fix bad logic in print_drs_error

2020-11-01T11:47:08Z

commit 1c9c02bb22684f6949d2e7ddc0a3ff364fd5a6fc upstream. Update logic for broken test. Use a more common logging style. It appears the logic in this function is broken for the consecutive tests of if (prog_status & 0x3) ... else if (prog_status & 0x2) ... else (prog_status & 0x1) ... Likely the first test should be if ((prog_status & 0x3) == 0x3) Found by inspection of include files using printk.

mtd: hyperbus: Replace HTTP links with HTTPS ones

2020-08-02T20:17:05Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

mtd: rawnand: Allocate the interface configurations dynamically

2020-06-26T06:35:08Z

Instead of manipulating the statically allocated structure and copy timings around, allocate one at identification time and save it in the nand_chip structure once it has been initialized. All NAND chips using the same interface configuration during reset and startup, we define a helper to retrieve a single reset interface configuration object, shared across all NAND chips. We use a second pointer to always have a reference on the currently applied interface configuration, which may either point to the "best interface configuration" or to the "default reset interface configuration".

mtd: rawnand: Get rid of the default ONFI timing mode

2020-06-26T06:35:08Z

The ->choose_interface() hook is here for manufacturer drivers to provide a better timing interface than the default one, this field is not needed anymore.

mtd: rawnand: Add the ->choose_interface_config() hook

2020-06-26T06:35:07Z

This hook can be overloaded by NAND manufacturer drivers to propose alternative timings when not following the main standards. In this case, the manufacturer drivers is responsible for choosing the best interface configuration that fits both the controller and chip capabilities.

mtd: rawnand: s/data_interface/interface_config/

2020-06-26T06:35:07Z

The name/suffix data_interface is a bit misleading in that the field or functions actually represent a configuration that can be applied by the controller/chip. Let's rename all fields/functions/hooks that are worth renaming. Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal

mtd: rawnand: Hide the chip->data_interface indirection

2020-06-26T06:35:06Z

As a preparation for allocating the data interface structure dynamically (and rename it), let's avoid accessing chip->data_interface directly. Instead, we introduce a helper, nand_get_interface_config(), and use it to retrieve the current data interface configuration out of a nand_chip object.

mtd: rawnand: Reorganize the nand_chip structure

2020-06-26T06:35:04Z

Reorder fields in this structure and pack entries by theme: * The main descriptive structures * The data interface details * Bad block information * The device layout * Extra buffers matching the device layout * Internal values * External objects like the ECC controller, the ECC engine and a private data pointer. While at it, adapt the documentation style. I changed on purpose the description of @oob_poi which was weird.
