linux-handhelds-2.6: Drop 2.6.20-hh1. Add 2.6.20-hh5.
* Changes since 2.6.20-hh4:
1. ts-adc-debounce: Use spec-originated formula for pressure calculation,
still needs tweaking for real world; implement pressure cut off properly,
and handle jitter in more sustainable manner: now samples with too much
jitter are ignored, not cause TS sampling to abort. Still needs further
elaboration to solve all outstanding issues and be able to support different
machines well.
2. Anton Vorontsov's ADC classdev refactor merged, all ADC API clients are
converted to it.
3. h5000: ADC/TS handling rewrote using ADC classdev. Light sensor support
added.
4. htcuniversal: tweak keys/switches handling and preliminary code to handle
PXA27x LCD controller features.
5. nand_base: Handle OOB operations more robustly.
6. ds1wm: Optmizations and more adherance to specs.
