2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?

2017-03-06ec/lenovo/h8: Use older syntax for bit shiftPaul Menzel
Currently, when using `iasl` 20140926-32 [Oct 1 2014] from Debian 8 (Jessie/stable), the build of the Lenovo X60 fails due to syntax errors. ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses the old syntax. So use `ShiftLeft` instead, which also fixes the build issue with older ASL compilers.

2017-02-28ec/lenovo/h8: Fix mute LEDsNicola Corna
thinkpad_acpi expects a SSMS method to turn on/off the mute LED and a MMTS method to turn on/off the microphone mute LED. With these methods implemented the driver can correctly sync the LEDs with the corresponding statuses. There seems to be two different bits to mute the audio in the Lenovo H8 EC: * AMUT, used internally (for example to disable the audio before entering S3). * ALMT, controllable by the OS, which also toggles the mute LED (if present). Tested on a X220T and on a X201.

2017-02-24ec/lenovo/h8: Guard against EC bugs in the battery status logic.Tobias Diedrich
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when the battery is nearly full and we switch from battery to AC by plugging in the cable, the current rate will not drop to 0 immediately, but the discharging state is cleared immediately. This leads to the code trying to process an invalid rate value >0x8000, leading to a displayed rate of >1000W. This patch changes the logic to deal with these corner cases.

2017-02-07ec/google/chromeec: let platform prepare for reboot when resetting ECAaron Durbin
This fixes an issue on systems where the S3 state in the pm1 control registers are not cleared when vboot determines recovery mode is required on an S3 resume. The EC code will reboot the system knowing that the EC was in RW. However, on subsequent entry into romstage the S3 path will be taken and fails to recover cbmem -- forcing another reboot. To work around that, signal to the platform a reboot is happening and let the platform perform the necessary fix ups to the register state.
