  I can second this, and even without reference to HTC or phone
devices: looking at sufficient scale, handheld hardware is of no
more variety than desktop one. And the drivers for most hardware are
already written, but oftentimes in an adhoc way, hardcoded for specific
device. So, what we need to do is refactor the codebase for drivers
to be reusable and promote best practice of this.

  What we should start with is apparently a hardware cross-reference
list, where you can lookup which handhelds use a specific chip. I took a
bite of this: http://handhelds.org/moin/moin.cgi/HandheldHardwareXref
. Hope this beginning will be supported.

  I also working on asic3_mmc refactor to bring SD/MMC support to all
ASIC3 devices (as of now it is harcoded for hx4700).

  If you ask me about another thing to do for ASIC3 is generic keys
driver: we have gpio_keys (former pxa_keys) driver for buttons
attached to CPU GPIOs, but many ASIC3 handhelds have some buttons
attached to ASIC3 GPIOs. Diffrent machines so far use adhoc drivers
for these (at least h1900, h4000), but there rather be one data-driven
driver (um, no pun ;-), paramterized for each machine.

P.S. I guess kernel-discuss is teh best list to discuss these things.
