Xiaobo Xie - Oct. 14, 2013, 11:37 a.m.
The QUICC Engine (QE) is a communications coprocessors on Freescale
embedded processors. The QE had been applied in PowerPC architecture
previously, and it will be applied in ARM architecture too.
So move the qe_lib from arch/powerpc to driver/ firstly.

Before this is moved you should address the PPC specific issues in the code.  Use of PPC_LIB_RHEAP, the IO macros which are not cross platform, etc.

Also, copy linux-kernel list as I'm not sure drivers/qe would be the recommendation location for this to end up at.

Additionally, some of this should move to using standard driver models that now exist.  For example qe_ic.{c,h} should possibly look at going into drivers/irqchip/.  gpio.c should be looked to use gpiolib and move into drivers/gpio.  Some of the pinmux that exists in qe.c and ucc.c should look at the drivers/pinctrl and there is some amount of clk config that I wonder if it could move the common clk API and drivers/clk.

There will still be some qe_lib specific code, but vastly reduced.

Greg,

Wondering your thoughts on drivers/qe vs something like drivers/soc/fsl/qe.  The QuiccEngine (qe) is a communication core on some of the Freescale networking SoCs that provides the ability to do various networking/communication functionality.  "Channels" on the QE can be used for various different things from ethernet, ATM, UART, or other functions.

I've already commented that some of what is in qe_lib today needs to move to things like drivers/irqchip, drivers/pinctrl, drivers/gpio, etc.  However, there will still be some qe specific code that doesn't have a natural home in drivers/ today.

What makes the code "QE" specific?  Are these devices that live on the
QE "bus", or are they controlling the QE controller?

It's hard to know what to do with code by just looking at a diffstat,
sorry.

Why not move it there now, instead of moving it twice?  How will I know
the move will ever happen if we accept it this way "for now"?

You may think of the QUICC as a "programmable bitbang machine" if
you like.  The very same component runs arbitrary and rather
different protocols depending on how you setup its parameters.

There have been serial controllers capable of different protocols
like UART or SPI or I2S, but all of them are "serial
communication".  There have been memory controllers which could
bitbang different protocols (NAND, NOR/SRAM, DRAM), but all of
them are "memory".

The QUICC is just a little more versatile, and appears to cover
cases which reside in different Linux kernel subsystems (like:
it's neither serial nor network exclusively, but can be either
and potentially more).

IIUC the question which Kumar Gala was asking is where to put
code for the component which is neither a strict subset of any
subsystem.  Please correct me if I'm wrong.

Thanks for the description.

Yeah, the actual ethernet, usb, serial drivers that exist with QE live today in proper drivers/ dirs.  This is the infrastructure that those drivers utilize that isn't quite related to an existing subsystem.  Mostly set up of channel state/cfg/etc.
